Abstract

Purpose

The Lattice Boltzmann (LB) method offers an alternative to conventional computational fluid dynamics (CFD) methods. However, its practical use for complex turbulent flows of engineering interest is still at an early stage. This paper aims to outline an LB wall-modeled large-eddy simulation (WMLES) solver.

Design/methodology/approach

The solver is dedicated to complex high-Reynolds flows in the context of WMLES. It relies on an improved LB scheme and can handle complex geometries on multi-resolution block structured grids.

Findings

Dynamic and acoustic characteristics of a turbulent airflow past a rod-airfoil tandem are examined to test the capabilities of this solver. Detailed direct comparisons are made with both experimental and numerical reference data.

Originality/value

This study allows assessing the potential of an LB approach for industrial CFD applications.

Abstract

Purpose

Emotional intelligence (EI) is a critical component of leadership that reflects the ability of leaders to understand how their emotions and actions affect the people around them in the organization. This paper aims to deliver state-of-the-art insights on EI and leadership.

Design/methodology/approach

This paper leverages on bibliometric analysis to unpack 25 years of EI and leadership research.

Findings

This paper reveals the bibliometric profile (e.g. trends in publication activity and top articles, authors, countries and journals) and intellectual structure (e.g. themes and topics) of EI and leadership research, shedding light on EI manifestation in leadership, EI and leadership congruence, EI role in leadership and EI and leadership for human resource management.

Research limitations/implications

This paper offers several noteworthy implications. First, EI is a leadership competency that can be cultivated and leveraged to improve leadership effectiveness. Second, the need for EI and leadership congruence indicates that leadership effectiveness is vital to human resource management (HRM). Taken collectively, these theoretical implications, and by extension, practical implications, suggest that increased investment in EI and leadership effectiveness is critical for organizations and their HRM.

Originality/value

This paper sheds light on current trends and ways forward for leading by feeling, showcasing the role and manifestation of EI in leadership, its value for HRM and the importance of its congruence for effective leadership in shaping the future of work.

Abstract

Purpose

In recent years, researchers have focused a great deal of attention on multirecess hybrid journal bearing systems. The non‐circular journal bearings are widely used in industry on account of their better stability, simplicity, efficiency and low cost. The purpose of this paper is to present a theoretical investigation into the performance of a two‐lobe multirecess hybrid journal bearing system.

Design/methodology/approach

The Reynold's equation governing the lubricant flow in the clearance space between the journal and bearing together with restrictor flow equations has been solved using finite element method. The bearing static and dynamic performance characteristics have been presented for the various values of the offset factors (0.75, 1, 1.25 and 1.50) for the hybrid mode of operation of the journal bearing system compensated by capillary and orifice restrictors for the commonly used bearing operating and geometric parameters. The offset of the journal has been accounted for by defining a non‐dimensional factor called offset factor delta.

Findings

The numerically simulated results indicate that a two‐lobe four recessed hybrid journal bearing provides a better performance than the corresponding similar circular recessed journal bearing system. The study further reveals that in order to get an improved performance of a two‐lobe four recessed journal bearing, a proper selection of bearing offset factors along with type of restrictor (capillary or orifice) is essential.

Originality/value

The results presented in this paper are useful for bearing designers.

Abstract

Purpose

The purpose of this study is to present factors associated with process barriers in implementing lean manufacturing within the small- and medium-sized enterprises (SMEs).

Design/methodology/approach

This study was conducted to identify the process barriers in implementing lean manufacturing in SMEs. Moreover, by a thorough and detailed analysis, process barriers of high rejection rate, employee absenteeism and frequent breakdown with 29 associated variables were identified as the most critical process barriers and were used to develop the questionnaire. Structural equation modeling was used to build the measurement model by drawing on samples of 128 SMEs in Kerala, a state in India. Later, the model was validated using statistical estimates. Data analysis helps to determine whether to accept or reject the hypothesis on the basis of the measurement model.

Findings

Several process barriers that prevent the successful implementation of lean manufacturing within SMEs are identified. These are lack of a training program, lack of periodical maintenance, low-quality standard materials from suppliers, bad vendor inspection, wear and tear of machines, communication gap between supervisors and workers, non-maintenance of a good employee–employer relationship, boredom on the job, overrunning machines beyond the capability, carelessness in work, not replacing worn damage parts periodically, ignoring warning signals of the machine classified as the most critical process barrier among the high rejection rate, employee absenteeism, frequent breakdown factors.

Research limitations/implications

First, the sample size of the study was relatively small (128). Second, data collection was restricted to one geographical area in India, i.e. Kerala, a state in India, giving rise to operational constraints. Third, the study was cross-sectional; a longitudinal study must be performed to reinforce the findings.

Practical implications

The present study has explored an unfocused area of lean implementation in SMEs. The results are expected to help researchers, academics and professionals in the domain of lean manufacturing.

Social implications

Governments of many countries around the world are helping and encouraging the implementation and understanding of the lean manufacturing system by providing financial assistance for training professionals and establishing professional associations. However, many industries have not been successful in lean implementation. This research aims to develop a strategy to tackle process barriers for successful lean implementation.

Originality/value

Very little research has been carried out in exploring process barriers in implementing lean manufacturing in SMEs. This paper will provide value to academics, researchers and practitioners of lean by providing insight into significant process barriers for lean implementation, especially in Indian industries.

Abstract

Purpose

The purpose of this paper is to present the factors associated with the employee barriers while implementing lean manufacturing within the small- and medium-scale enterprises (SMEs).

Design/methodology/approach

The structural equation modelling approach is employed to develop the initial model drawing a sample survey of 133 small and medium enterprises. The result of the study shows that the lack of well-trained and experienced staff, lack of knowledge about existing specialist, cultural resistance to change are acting as the employee barriers while implementing lean manufacturing in SMEs. Then, a further study has been conducted to develop the employee barrier model with these three factors and its contributing variables using specification search representing the sample of 117 small and medium enterprises using the following fit function criteria: Chi-square (C), Chi-square-df (C-df), Akaike information criteria, Browne-Cudeck criterion, Bayes information criterion, Chi-square divided by the degrees of freedom (C/df) and significance level (p).

Findings

The lack of well-trained and experienced staff, lack of knowledge about existing specialist, and cultural resistance to change with 19 associated elements were considered in the questionnaire. Specification search was carried out to build up the model on the collected data from 117 SMEs. The results of the specification search identified that these three factors with 15 key variables are significant to employee barrier while implementing lean manufacturing in SMEs.

Research limitations/implications

The limitation of the study was that the sample size of the study was relatively small for further research, large sample size more than 117 are to be expected.

Practical implications

The present study has explored an unfocused area of lean implementation in small and medium enterprises. The results obtained from the study are expected to help researchers, academics, and professionals for the further studies in the domain of lean manufacturing.

Social implications

To implement and understand the lean manufacturing system, government of the many countries around the world are helping and encouraging by providing financial assistance for training professionals and establishing professional associations. However, many industries are not successful in lean implementation. This research work provides to develop a strategy to tackle employee barriers for successful lean implementation.

Originality/value

Very little research has been carried out exploring employee barriers while implementing lean manufacturing in SMEs. This paper will provide value to academics, researchers and practitioners of lean by way of providing insight into significant employee barriers for lean implementation, especially in Indian industries.

Abstract

Purpose

The paper aims to devise an externally adjustable fluid film bearing whereby the hydrodynamic conditions can be changed as required in a controlled manner. Unlike a tilting pad bearing, in this bearing film thickness can be varied by providing radial and tilt adjustments to the pad, irrespective of the operating conditions. This variation in film thickness in‐turn varies the stiffness and damping coefficients.

Design/methodology/approach

The stability characteristics of a centrally loaded 120° single pad externally adjustable fluid film bearing is studied theoretically. The bearing has an aspect ratio of one and operates over a wide range of eccentricity ratios and adjustments. The time dependent form of Reynolds equation in two dimensions is solved numerically using the finite difference method. Dynamic performance characteristics of the bearing are in terms of film stiffness and damping coefficients, critical mass of the journal and the whirl frequency ratio. Stability is determined using a first‐order‐linear‐perturbation method.

Findings

The paper finds that a study with various adjustments predicts that negative radial and negative tilt adjustment configuration results in superior dynamic characteristics as compared to a conventional fluid film bearing.

Originality/value

It is possible to have a particular set of radial and tilt adjustments that will provide a stable operation of the rotor bearing system. Single pad externally adjustable fluid film bearing will perform as a conventional partial arc bearing when both the adjustments are set to zero.

Abstract

Purpose

This study aims to embark on a bibliometric journey through the International Journal of Retail & Distribution Management (IJR&DM) to delve into its rich repository of applied retailing research.

Design/methodology/approach

626 publications in IJR&DM between 2015 and 2023 have been retrieved from Scopus for performance analysis of the journal’s publication (productivity) and citation (impact) trends as well as a science mapping of the journal’s collaborators (contributors) and major themes (contributions).

Findings

The performance analysis highlights the growth in the productivity and impact of IJR&DM alongside its most cited publications, most prolific contributors, most relied-on journals, as well as the authors, institutions, countries, and journals that the journal has impacted the most. The co-authorship analysis reveals the collaboration (i.e., international with a high concentration in Europe and North America along with an emerging presence in Asia) of IJR&DM. Keyword co-occurrence analysis and bibliographic coupling reveal eight themes. Our exploration revealed close interconnections among various domains including retailing and adaptive strategies, channel strategies, customer experience, market innovations, operations management, relationship marketing, shopping motivation, and sustainability.

Research limitations/implications

Although this study delivers a state-of-the-art overview of the retail industry through the scientific contributions from IJR&DM, it remains limited to the insights from a single authoritative source of knowledge on retailing.

Originality/value

No review, to date, has been conducted for IJR&DM. This study provides the inaugural retrospective of the scientific contributions of IJR&DM, outlining publication and citation trends alongside the intellectual structure of its body of knowledge on retailing. Theoretically, this retrospective is pivotal in charting the intellectual growth and thematic nuances inherent in retail research. Practically, this study serves as a guide for practitioners, enabling them to make strategically informed decisions and craft forward-looking strategies in sync with current realities.
