Abstract

Purpose

This study aims to numerically analyse a full-scale burner across a wide range of operating pressure conditions and determine the effect of swirl velocity on flame stabilization, flame holding and combustion performance.

Design/methodology/approach

This study uses a numerical analysis approach to investigate a three-dimensional full-scale burner. Modified governing equations are used to determine the effect of swirl velocity on flame stabilization and flame holding. The GR-Mech 3.0 chemical reaction mechanism is used to predict the combustion process. To validate the model, a grid independence study is performed.

Findings

The study reveals that swirl velocity enhances flame stability, resulting in better combustion rates. As the swirl velocity increases, higher flame temperatures are observed due to high convective heat recirculation. The heat transfer coefficient and high radiative extinction coefficient are found to vary based on fuel swirl velocity. The mass fraction of CH4 and CO emphasizes the role of swirl velocity on flame structure. Increasing velocity potentially improves combustion by delaying the process, leading to better combustion and lower emissions.

Originality/value

The findings of this study contribute to the understanding of swirl-stabilized combustion and can guide the development of advanced combustion technologies, making it a valuable addition to the existing combustion field.

Abstract

Purpose

This study aims to study the interaction effects between a rectangular supersonic jet with a flat wall computationally using wall length as a parameter. The purpose of this study is to investigate the effect of change in wall length on supersonic core length (SCL) reduction, jet deflection and jet decay behavior.

Design/methodology/approach

The design Mach number and aspect ratio at the rectangular exit were 1.8 and 2, respectively. To study the wall length effects on jet-wall interactions, wall length (Lw) was varied as 0.5Dh, 1Dh, 2Dh, 4Dh and 8Dh, where Dh was the hydraulic diameter of the nozzle exit. The flat wall with the matching width of the rectangular exit section of a supersonic nozzle was placed at the nozzle exit such that the supersonic jet grazed past the wall. The studies were carried out at over-expansion [nozzle pressure ratio (NPR) = 4], near optimum expansion (NPR = 6) and under-expansion (NPR = 8) levels.

Findings

Results indicated that significant reduction in wall-bounded SCL was noticed in the range of 0.5Dh Lw 1Dh for both over-expansion and under-expansion conditions. At Lw 4Dh, SCL got enhanced at NPR = 4 and 6 but had a negligible effect at NPR = 8.

Practical implications

Thrust vector control, noise reduction and easy take-off for high-speed aircraft.

Originality/value

The effect of change in flat wall length on interaction characteristics of a rectangular supersonic jet was not studied before in terms of SCL reduction and jet decay behavior.

Abstract

Purpose

This paper aims to focus on the issue of high employee turnover in the Indian tech industry. An integrative review is conducted to analyse the past and current state of literature, as well as prepare a research agenda for future studies.

Design/methodology/approach

A pool of 72 articles published between 2010 and 2022 is reviewed with a special focus on Indian tech employees. This study elucidates the extent and impact of employee retention strategies through content analysis.

Findings

Two broad perspectives have been established in the literature: the reasons for quitting and the explanations for staying. By means of a comprehensive review, this paper combines these two aspects of literature and suggests factors under organization’s control to retain competent tech employees.

Originality/value

The study is designed to integrate the two theoretical viewpoints of employee turnover literature by consolidating the reasons behind quitting behaviour and staying intention. Codes combining the two aspects are presented as a valuable resource to retain tech talent.

Abstract

Purpose

The purpose of this study is to identify organisational homeostasis factors in the context of healthcare organisations and to develop a conceptual model for green transformation.

Design/methodology/approach

The organisational homeostasis factors were determined by review of literature study and the opinions of healthcare experts. Scheduled interviews and closed-ended questionnaires are employed to collect data for this research. This study employed “TISM methodology” and “MICMAC analysis” to better comprehend how the components interact with one another and prioritise them based on their driving and dependence power.

Findings

This study identified 10 factors of organisational homeostasis in healthcare organisation. Recognition of interdependence, hormesis, strategic coalignment, consciousness on dependence of healthcare resources and cybernetic principle of regulations are the driving or key factors of this study.

Research limitations/implications

The study's primary focus was on the organisational homeostasis factors in healthcare organisations. The methodological approach and structural model are used in a healthcare organisation; in the future, these approaches can be applied to other industries as well.

Practical implications

The key drivers of organisational homeostasis and the identified factors will be better comprehended and understood by academic and important stakeholders in healthcare organisations. Prioritizing the factors helps the policymakers to comprehend the organisational homeostasis for green transformation in healthcare.

Originality/value

In this study, the TISM and MICMAC analysis for healthcare is proposed as an innovative approach to address the organisational homeostasis concept in the context of green transformation in healthcare organisations.

Abstract

Purpose

The purpose of this paper is to empirically analyze the impact of remittance inflows on sustained economic growth in India.

Design/methodology/approach

This study has taken a time series dataset for the period of 1976–2021, and a nonlinear autoregressive distributed lag model technique (NARDL) has been applied to check the impact of remittance inflows along with other control variables, including broad money and service sector performance, on the sustained economic growth of India.

Findings

The results of the study indicated that in both the short and long runs, any positive shock in remittance inflows has a positive impact on the economic growth of India, while negative shocks do not affect economic growth.

Practical implications

The economic policymakers of India can use the findings of the study by implementing remittance-friendly policies. Moreover, NITI Aayog, the body working toward achieving sustainable development goals (SDGs) in India, can also use this study as a reference while making strategies to achieve SDG.

Originality/value

Economic growth has always been an area of interest among economists, researchers and policymakers. However, achieving sustained economic growth requires an analysis of those factors that themselves have sustained performance over a long period of time and have the potential to sustain it over the upcoming years. This study has taken remittance inflows as one such factor and investigated its impact on the sustained economic growth of India. At present, there is an evident gap in the literature that very little attention has been given to sustained Indian economic growth. Moreover, there is no study available in which the nonlinear impact of different variables has been tested on the economic growth of India.

Abstract

Purpose

The current paper aims to discuss the implementation of Green Lean Six Sigma (GLSS) in the food industry to improve sustainable practices. The focus is more specifically on dairy processors to ascertain the current state of the literature and aid future research direction.

Design/methodology/approach

Utilising a systematic literature review (SLR), the paper addresses various terms and different written forms in the literature. The study characterises the current deployment of GLSS in the food industry and explains the reported benefits of this approach.

Findings

GLSS, a concept that has yet to be fully explored in the food industry, as in other sectors, holds significant potential to enhance the food industry’s sustainability practices. The dairy sector, a subsector of the food industry known for its high greenhouse gas emissions, is a prime candidate for the application of GLSS. In instances where it has been applied, GLSS has demonstrated its effectiveness in improving sustainability, reducing waste, lowering greenhouse gas emissions and minimising water usage. However, the specific tools used and the model for GLSS implementation are areas that require further study, as they have the potential to revolutionise food industry operations and reduce their environmental impacts.

Practical implications

Benchmarking of this research by the food industry sector and by academics can aid understanding of the practical application of GLSS tools and aid implementation of these practices to evolve the dairy processing sector in the next decade as sustainability champions in the sector.

Originality/value

This study extensively analyses GLSS in the food industry, with a particular focus on dairy processors.

Abstract

Purpose

It is observed that bank transactions are at the top of the list as consumers' online transactions increase day by day. We assume that creating an emotion-rich experience will be more effective in ensuring brand awareness, brand associations, perceived quality and brand loyalty, which affect the creation of consumer-based brand value. In this study, it is aimed to determine the relationship of the emotional brand experiences of internet banking users in the brands they use on creating consumer-based brand equity.

Design/methodology/approach

The data in the answers of 484 participants among the 504 people who filled out the questionnaire on social media with the snowball sampling method and were determined to have consistent answers and stating that they used internet banking, were analyzed by SPSS and Structural Equation Modeling (SEM).

Findings

The emotional experiences of internet banking users in Turkey with the internet brand they use have a relationship on all four dimensions (brand awareness, brand loyalty, brand associations and perceived quality) that make up consumer-based brand equity. In this study, the relationship was determined as brand awareness, brand loyalty, perceived quality and brand associations, respectively. The dimensions of the relationship of internet banking users emotional brand experience and consumer-based brand equity were supported.

Research limitations/implications

The research was carried out with internet banking users in Turkey. The results of this research can be compared with studies to be conducted in different countries and with different product brands. In addition, the level of contribution can be increased by investigating the emotional brand experience by comparing positive and negative emotions.

Practical implications

As online connection allowing instant access to unrecognized places and being able to reach brands from long distances instantly makes the emotional experience that can create emotional attachment between the brand and the customer, and brand awareness, brand loyalty, brand association and perceived quality, which are the dimensions of consumer-based brand equity affected by emotional experience, much more important. This importance is increasing day by day as the positive emotional experience to be created in banking services is directly related to access to money. Banking transactions are generally considered as cognitive transactions, and decisions are made and implemented within a cognitive context. However, the findings of this research suggest that decisions should be made and implemented that will enable consumers to gain experiences that can affect their emotions as well as their cognition.

Originality/value

Considering the importance of strategies and tactics that prioritize the creation of consumer-based brand equity in marketing theory, the importance of adding emotional brand experience to these strategies and tactics is supported by the results of this research as originality value. Although the effect of brand experience on consumer-based brand value has been widely researched in the literature, the fact that the effect of brand experience, especially emotional brand experience, on consumer-based brand experience in internet banking transactions has not been sufficiently researched and that this effect has been investigated specifically for Turkey, unlike the literature, increases the original contribution of the research.

Abstract

Purpose

This study aims to explain the relationships between dynamic capabilities, product innovation, firm performance and technology uncertainty.

Design/methodology/approach

The quantitative research method was the preferred approach. Data were collected through a questionnaire from managers working in different sectors. The study’s sample consists of 619 managers from 226 different firms.

Findings

The findings show that there is a positive relationship between dynamic capabilities and product innovation and that dynamic capabilities have a positive relationship with firm performance. In addition, the findings indicate a significant positive mediating effect of product innovation on the relationship between dynamic capabilities and firm performance. Another key finding is the positive moderation effect of technology uncertainty on the relationship between product innovation and firm performance.

Research limitations/implications

Using a single sample (country) limits generalizability due to differences in economic structure and market dynamics. Furthermore, by focusing only on product innovation, the role of other types of innovation is not considered.

Practical implications

This study emphasizes that, especially in environments with high technology uncertainty, it is important to develop dynamic capabilities for better firm performance as well as turn these capabilities into tangible outputs such as product innovation.

Originality/value

This study examines the relationship between dynamic capabilities and firm performance, which is frequently discussed and extremely important for the literature, from different perspectives within the context of an emerging economy. In addition to the direct relationship between dynamic capabilities and firm performance, the contribution of dynamic capabilities to performance through product innovation, which is an ordinary capability, (together with the moderating effect of technological uncertainty) was investigated.

Abstract

Purpose

This study aims to investigate the impact of service quality (SQ), perceived value (PV) and consumer satisfaction on Thai street food, with customer satisfaction (CS) as a mediator for customer loyalty and repurchase intention (RI). It also explores how consumer trust (CT) in Thai street food safety moderates these relationships.

Design/methodology/approach

Structural equation modelling (SEM) was utilised to analyse the complex interrelationships between various constructs. Multi-group analyses were conducted to investigate the moderating effects of CT on the structural model, considering two distinct groups based on trust levels: low and high.

Findings

The findings revealed that SQ and PV significantly influenced CS and behavioural intention, while the perceived quality of Thai street food had no significant impact on post-COVID-19 consumer satisfaction. The study highlighted the critical role of CT in moderating the relationships between SQ, PV and CS, with distinct effects observed in groups with varying trust levels.

Social implications

The research emphasises the importance of enhancing SQ and delivering value to customers in the context of Thai street food, which can contribute to increased CS, RI and positive word-of-mouth. Furthermore, the study underscores the critical role of building CT in fostering enduring customer relationships and promoting consumer satisfaction and loyalty.

Originality/value

This research offers valuable insights into consumer behaviour and decision-making processes, particularly within the realm of Thai street food. It underscores the significance of understanding and nurturing CT, especially in the post-COVID-19 landscape, emphasising the need for effective business strategies and consumer engagement.
