Magnetohydrodynamic Peristaltic Flow of Pseudoplastic Fluid in a Vertical Asymmetric Channel Through Porous Medium with Heat and Mass Transfer

This investigation deals with the influence of heat and mass transfer on magnetohydrodynamic peristaltic flow of Pseudoplastic fluid in a vertical asymmetric channel through porous medium. The flow is examined in the wave frame of reference moving with the velocity of the wave. For formulation of the problem, long wavelength and low Reynolds number assumptions are taken into account. The perturbation solution has been derived for the stream function and pressure gradient. The pressure difference is calculated numerically. The influence of various parameters of interest on velocity, pressure gradient, temperature, concentration, pressure difference, heat transfer coefficient and trapping has been investigated graphically. The graphical results are also discussed for four different wave shapes. It is found that, in all the cases the magnetic parameter and Darcy number have opposite effect on the flow variables. The size of the trapped bolus increases from porous medium to non-porous medium and it decreases with increase of magnetic effects.
