Abstract

In this work the significance of Cross Diffusion effect on unsteady MHD peristaltic flow in a porous medium with heat and mass transfer is investigated. The governing partial differentialequations are transformed into dimensionless equations by using dimensionless quantities. Stream function, velocity, temperature, concentration, skin friction, Nusselt number and Sherwood number are obtained. The results are discussed for various emerging parameters encountered in the problem under investigation. The importance of main parameters on the present study is explained graphically

Highlights

The heat and mass transfer of an unsteady MHD flow attracted by the researchers, because it is most useful to many fields such as production process, chemical-engineering application of a physical and the peristaltic flow used in pump and other mechanical systems.The most important mechanism of fluid transport is peristalsis and it is formed by the propagation of a peristaltic wave on the channel walls
Keeping in mind the importance of heat and mass transfer of an MHD Peristaltic fluid with cross diffusion effects in porous medium under the influence of inclined magnetic field, we have gone for a detailed study

INTRODUCTION

The heat and mass transfer of an unsteady MHD flow attracted by the researchers, because it is most useful to many fields such as production process, chemical-engineering application of a physical and the peristaltic flow used in pump and other mechanical systems.The most important mechanism of fluid transport is peristalsis and it is formed by the propagation of a peristaltic wave on the channel walls. The effects of MHD couple stress fluid in peristaltic flow with the porous medium under the impact of slip, heat transfer and wall properties attempted by Sankad, G. The effect of heat transfer and inclined magnetic field on the peristaltic flow of williamson fluid in an asymmetric channel through porous medium is investigated by Ramesh, K. and Devakar, M. Keeping in mind the importance of heat and mass transfer of an MHD Peristaltic fluid with cross diffusion effects in porous medium under the influence of inclined magnetic field, we have gone for a detailed study. The stream function is used to solve governing coupled nonliner partial differential equations
