Dynamics of the thermally radiative and chemically reactive flow of Sisko fluid in a tapered channel

Abstract

This paper addresses the analysis of chemical reaction for peristaltic movement of electrically conducting Sisko fluid in an asymmetric tapered channel with velocity slip condition. An incompressible Sisko fluid saturates the porous medium. Modified Darcy’s law has been employed for the porous medium effect. The impacts of thermal radiation and viscous dissipation are also taken into account. The resultant non-linear expressions are solved based on the approximation of lubrication theory. Such consideration is significant to predict human physiological characteristics especially in blood flow problems. The analytical outcomes for velocity, streamlines, pressure gradient, and temperature equations are found by utilizing the regular perturbation technique. The graphical illustrations are provided to explain the impressions of numerous emerging parameters on flow fields. The significant results of the current studies are that fluid velocity enhances for Darcy number and Sisko fluid parameter.
