Abstract

As a model for hazardous material pumps, this article examines the magnetohydrodynamic chemically reacting thermo-solutal peristaltic transport of a non-Newtonian couple stress fluid through a microchannel containing a porous medium. The effects of thermal radiative heat transfer, Joule heating, Soret thermo-diffusion, viscous dissipation and heat generation/absorption are also included. The microchannel walls have convection boundary conditions and sinusoidal peristaltic waves are considered. The conservation equations for mass, momentum, energy and concentration are simplified via lubrication approximations. The moving boundary value problem is rendered dimensionless and solved analytically. Numerical evaluations of the axial velocity, temperature and concentration are conducted in MATLAB. Bejan number is enhanced with couple stress (non-Newtonian) parameter, mean flow rate and Brinkman number. Temperatures are boosted with Hartmann (magnetic) number and Brinkman number but suppressed with couple stress parameter. Entropy generation parameter is reduced with increment in couple stress parameter and radiation parameter whereas it is boosted with Brinkman number. Pressure gradient is enhanced with increment in Hartmann (magnetic) number but depleted with Darcy number and couple stress parameter. Concentration is strongly reduced in the core zone of the channel with increment in Soret number, Brinkman number, Hartmann number, mass Biot number and Schmidt number, but increased with chemical reaction parameter. Nusselt number magnitudes are elevated with thermal Biot number, Brinkman number, couple stress parameter and magnetic parameter but 2 are reduced with increasing radiation parameter. A substantial modification in bolus size is induced with increasing Hartmann number, Darcy number and couple stress parameter.
