Abstract

The presented article addresses the electro-osmotic peristaltic flow of a couple stress fluid bounded in an inclined asymmetric micro-channel. The viscous dissipation, Joule heating and chemical reaction effects are employed simultaneously in the flow analysis. Heat and mass transfer have been studied under large wavelength and small Reynolds number. The resulting nonlinear systems are solved numerically. The influence of various dominant physical parameters is discussed for velocity, temperature distribution, concentration distribution and the pumping characteristics. Electro kinetic flow of fluids by micro-pumping through micro channels and micro peristaltic transport has accelerated considerable concern in accelerated medical technology and several areas of biomedical engineering. Deeper clarification of the fluid dynamics of such flow requires the continuous need for more delicate mathematical models and numerical simulations, in parallel with laboratory investigations.

Summary

Introduction

Recent investigations in miniaturization and micro-fabrication have taken into assuming a lot of applications extending from organic to refrigerating of microelectronics in [1,2,3,4,5,6,7,8,9]. The transfer of heat investigation of osmotic electro motion in a slowly varying non-symmetric micro-channel is presented in [11]. The important focus of this study is to investigate the viscous dissipation, Joule heating effects on MHD electro-osmotic peristaltic transport of couple stress fluid in an inclined asymmetric micro channel. 2 Methodology We analyze the peristaltic electro-osmotic transport of incompressible couple stress fluid which is electrically conducting and transfers of heat through asymmetric inclined micro-channel walls with charged under the impact of a promulgated the magnetic field. 2.2 Couple stress fluid model The given set of pertinent field equations governing the flow, in laboratory frame is [12, 33]:. 8 to 11 depict the deviations in temperature profiles for various values of parameters A, k, Rd and Ec.
