Abstract

Purpose

The purpose of this study is to find out the relationship between the corporate social responsibility (CSR) and green performance (GP) of Pakistani manufacturing SMEs. This study further explores the mediating roles of green human resource management (GHRM) and green innovation (GI) in the relationship between CSR and GP.

Design/methodology/approach

A survey method was used to collect data from manufacturing SMEs. Data were collected from 366 respondents working in higher positions and playing a decisive role in the organization. The collected data were analysed by applying structural equation modelling with the help of smart PLS.

Findings

The study shows that CSR (customers, society, employees) helps significantly improve a firm's GP. Furthermore, this study explores how GI (process, product) and GHRM (skills development, motivation and involvement) mediate the relationship between CSR and GP.

Research limitations/implications

This study is limited to manufacturing SMEs and a single developing country, Pakistan. However, this study will significantly contribute to the existing literature on GP and help manufacturing firms’ top management take steps to minimize carbon emissions and improve GP. Furthermore, this study will also provide valuable insights to government agencies in the Asian context to adjust their policies regarding the manufacturing sector to reduce pollution in the country.

Originality/value

As a pioneering study encompassing CSR, GHRM, GI and GP under one research paradigm in an emerging economy environment, the current research provides substantial additions to the literature on the impact of CSR on GP.

Abstract

Purpose

In the modern business world, the main focus of the organizations is to improve the quality of the products and minimize the wastage of raw material. Keeping in view the green theory and improve the efficiency of the organization, the focus of the current study is to investigate the relationship between total quality management (TQM) and green innovation (GI), and examine how TQM practices can facilitate firms to achieve GI objectives. Corporate social responsibility (CSR) is also an important factor for organizations, and this study also focuses on the mediating role of CSR between the relationship of TQM and GI.

Design/methodology/approach

This is an empirical study. Data were gathered from the top management of 355 SMEs working in Pakistan through a questionnaire survey; the PLS-SEM approach was used to analyse the data.

Findings

Results of the study show that TQM has significant impacts on two aspects of GI namely green product innovation and green process innovation. Moreover, results also reveal that CSR partially mediates the relationship between TQM and GI.

Research limitations/implications

This study is limited to manufacturing SMEs and future research should test this model on non-manufacturing sector too. The findings of the study provide significant roadmap to the management of small and medium-sized manufacturing firms that how they can reduce wastage and improve the product and process innovation in their organizations through TQM and CSR.

Originality/value

This study contributes to bridging research gaps in the literature and advances how TQM, directly and indirectly, help firms improve green innovation via mediating roles of CSR.

Abstract

Purpose

The purpose of this paper is to focus on MHD unsteady flow of Carreau fluid over a variable thickness melting surface in the presence of chemical reaction and non-uniform heat sink/source.

Design/methodology/approach

The flow governing partial differential equations are transformed into ordinary ones with the help of similarity transformations. The set of ODEs are solved by a shooting technique together with the R.K.–Fehlberg method. Further, the graphs are depicted to scrutinize the velocity, concentration and temperature fields of the Carreau fluid flow. The numerical values of friction factor, heat and mass transfer rates are tabulated.

Findings

The results are presented for both Newtonian and non-Newtonian fluid flow cases. The authors conclude that the nature of three typical fields and the physical quantities are alike in both cases. An increase in melting parameter slows down the velocity field and enhances the temperature and concentration fields. But an opposite outcome is noticed with thermal relaxation parameter. Also the elevating values of thermal relaxation parameter/ wall thickness parameter/Prandtl number inflate the mass and heat transfer rates.

Originality/value

This is a new research article in the field of heat and mass transfer in fluid flows. Cattaneo–Christov heat flux model is used. The surface of the flow is assumed to be melting.

Abstract

Purpose

The effect of non-linear thermal radiation and variable thermo-physical properties are investigated in the Falkner-Skan flow of a Casson nanofluid in the presence of magnetic field. The paper aims to discuss this issue.

Design/methodology/approach

Selected bunch of similarity transformations are used to reduce the governing partial differential equations into a set of non-linear ordinary differential equations. The resultant equations are numerically solved using Runge-Kutta-Fehlberg fourth-fifth-order method along with shooting technique.

Findings

The velocity, temperature and concentration profiles are evaluated for several emerging physical parameters and are analyzed through graphs and tables in detail.

Research limitations/implications

This study only begins to reveal the research potential and pitfalls of research and publishing on boundary-layer flow, heat and mass transfer of Casson nanofluid past and the moving and static wedge-shaped bodies.

Originality/value

It is found that the presence of non-linear thermal radiation and variable properties has more influence in heat transfer. Furthermore, temperature profile increases as the radiation parameter increases.

Abstract

Purpose

The purpose of this paper is to scrutinize the heat and mass transfer attributes of three-dimensional bio convective flow of nanofluid across a slendering surface with slip effects. The analysis is carried out subject to irregular heat sink/source, thermophoresis and Brownian motion of nanoparticles.

Design/methodology/approach

At first, proper transmutations are pondered to metamorphose the basic flow equations as ODEs. The solution of these ODEs is procured by the consecutive application of Shooting and Runge-Kutta fourth order numerical procedures.

Findings

The usual flow fields along with density of motile microorganisms for sundry physical parameters are divulged via plots and scrutinized. Further, the authors analyzed the impact of same parameters on skin friction, heat and mass transfer coefficients and presented in tables. It is discovered that the variable heat sink/source parameters play a decisive role in nature of the heat and mass transfer rates. The density of motile microorganisms will improve if we add Al-Cu alloy particles in regular fluids instead of Al particles solely. A change in thermophoresis and Brownian motion parameters dominates heat and mass transfer performance.

Originality/value

To the best of the knowledge, no author made an attempt to investigate the flow of nanofluids over a variable thickness surface with bio-convection, Brownian motion and slip effects.

Abstract

Purpose

The purpose of this paper is to examine outcome of activation energy in rotating flow of an Oldroyd-B nano liquid.

Design/methodology/approach

Flow is generated due to stretched surface. Binary chemical reaction is studied. Brownian and thermophoresis effects are considered. The system of nonlinear ordinary differential equations is derived. Convergent series solutions are obtained by homotopy analysis method. The resulting expressions for velocities, temperature and concentration are computed for different embedded parameters.

Findings

It is found that velocities f′ and g  have decreasing effect when rotation parameter is enhanced. Brownian and thermophoresis are increasing functions of temperature and concentration. The physical quantities are sketched and discussed numerically. Concentration and temperature fields show decreasing behavior via Brownian and thermophoresis parameters.

Originality/value

Abstract

Purpose

The purpose of this paper is to study entropy generation in magneto-Jeffrey nanomaterial flow by impermeable moving boundary. Adopted nanomaterial model accounts Brownian and thermophoretic diffusions. Modeling is arranged for thermal radiation, nonlinear convection and viscous dissipation. In addition, the concept of Arrhenius activation energy associated with chemical reaction are introduced for description of mass transportation.

Design/methodology/approach

Homotopy algorithms are used to compute the system of ordinary differential equations.

Findings

The afore-stated analysis clearly notes that simultaneous aspects of activation energy and entropy generation are not yet investigated. Therefore, the intention here is to consider such effects to formulate and investigate the magneto-Jeffrey nanoliquid flow by impermeable moving surface.

Originality/value

As per the authors’ knowledge, no such work has yet been published in the literature.

Abstract

Purpose

The purpose of this paper is to address the impact of induced magnetic field in mixed convective stagnation flow of TiO2-Cu-water hybrid nanofluid towards a stretchable sheet. Non-linear thermal radiation and heat source/sink are accounted. Flow of hybrid nanofluid is discussed. Non-linear partial differential expressions are converted to ordinary ones through appropriate transformations.

Design/methodology/approach

The obtained systems are solved for convergence solutions via homotopy analysis method. Graphical results are discussed for different physical variables on the velocity, induced magnetic field and temperature fields for both Cu water nanofluid and TiO2-Cu-water hybrid nanofluid. Finally, the effect of different physical variables on skin friction coefficient (Cfx) and Nusselt number Nux in the presence of water nanofluid and TiO2-Cu-water hybrid nanofluid are discussed.

Findings

Velocities and induced magnetic field are increasing functions of mixed convection parameter and nanoparticle volume fraction. Temperature rises for higher radiation parameter. Skin friction is greater in case of Cu-water nanoliquid, while Nusselt number is less for Cu-water nanofluid when they are compared with hybrid nanoliquid TiO2-Cu-water.

Originality/value

No such work is not yet present in the literature.

Abstract

Purpose

This study aims to examine the flow characteristics of Ree–Eyring fluid between two rotating disks. The characteristics of heat transfer are discussed in presence of viscous dissipation, heat source/sink and nonlinear radiative heat flux.

Design/methodology/approach

Nonlinear flow expressions lead to ordinary ones through adequate similarity transformations. The ordinary differential system has been tackled through optimal homotopic method. The impact of different flow variables on the velocity field, entropy generation rate and temperature fields is graphically discussed. The surface drag force and heat transfer rate are numerically examined via various pertinent parameters.

Findings

By minimization of values of stretching parameter and Brinkman number, the entropy generation rate can be controlled. The entropy generation rate enhances for higher values of magnetic parameter, while the Bejan number is decreased via magnetic parameter.

Originality/value

No such work is yet published in the literature.
