Abstract

ABSTRACTIn this article, combined effects of magnetohydrodynamics (MHD) heat transfer flow under the influence of slip over a moving flat plate are investigated. Effects of entropy generation are also examined. A set of non-dimensional resulting equations are solved by means of Bvp4c Matlab package. The role of flow parameters like magnetic parameter and slip parameter on flow velocity profile and temperature profile are presented and elaborated through graphs. The expressions for entropy generation and flow against Bejan number are also examined. The obtained results reveal that for various values of slip parameter, the Bejan number (Be) decreases for , whereas opposite behaviour is noted for .

Summary

Introduction

Mechanism of heat transport on a roving solid surface plays a significant role in extrusion of plastic sheets, crystal growth, polymer industry, paper production, liquid film and in condensation processes. Rashidi et al [6] have used similarity variables to examine the mixed convective flow with MHD, slip and thermal convective boundary condition along with a moving vertical flat surface. Martin and Boyd [8] discussed the partial slip effect on laminar boundary layer flow and heat transfer over a flat surface. Bhattacharyya et al [11,12] presented the impact of uniform magnetic field embedded with porous medium on boundary layer flow with slip effect over flat plate. Inspired by the previous researchers, the determination of this effort is to observe theatrically the entropy generation analysis on boundary layer flow past a flat moving surface under the combined impact of induced magnetic field and momentum slip condition. Where Re denotes local Reynolds number, f (0) and −θ (0) represent reduced skin friction and Nusselt number
