Peristaltic Transport of a Physiological Fluid in an Asymmetric Porous Channel in the Presence of an External Magnetic Field

TL;DR

This paper provides a theoretical analysis of how a magnetic field influences peristaltic transport of physiological fluids in asymmetric porous channels, highlighting effects on velocity, pressure, and flow patterns.

Contribution

It introduces a comprehensive analytical and numerical study of magnetic and porous effects on peristaltic flow, extending previous non-porous, non-magnetic models.

Findings

Magnetic field significantly alters flow characteristics.

Permeability and phase difference impact trapping and flow efficiency.

Results align with previous non-magnetic, non-porous studies.

Abstract

The paper deals with a theoretical investigation of the peristaltic transport of a physiological fluid in a porous asymmetric channel under the action of a magnetic field. The stream function, pressure gradient and axial velocity are studied by using appropriate analytical and numerical techniques. Effects of different physical parameters such as permeability, phase difference, wave amplitude and magnetic parameter on the velocity, pumping characteristics, streamline pattern and trapping are investigated with particular emphasis. The computational results are presented in graphical form. The results are found to be in perfect agreement with those of a previous study carried out for a non-porous channel in the absence of a magnetic field.
