摘要：

We examined the effect of velocity slip on hydromagnetic peristaltic flow of a Casson fluid and heat transfer through an asymmetric channel fluid filled with a porous medium. The equations governing the model were obtained, simplified using long wavelength and low Reynolds number assumptions, and then tackled analytically. Numerical results for the effects of the embedded parameters on the stream function, axial velocity, pressure drop, temperature, skin friction, and Nusselt number are presented graphically and discussed in this study. It was found that the permeability parameter enhanced the size of the trapped bolus, while velocity slip diminished it. A rise in magnetic field intensity and Casson fluid parameters decreased both velocity and temperature profiles. The presented problem is of substantial importance in crude oil refinement and biomedical engineering. (C) 2019 Sharif University of Technology. All rights reserved.
