The purpose of this study is to analyze the influence of wall flexibility and cross diffusion on the peristaltic transport of a MHD dissipative fluid in uniform channel in the presence of Joule heating. Dual solutions are obtained for aligned and transverse magnetic field cases. The exact solution is obtained for stream function and velocity. Further, shooting process is employed to solve the energy and concentration equations. The influence of main parameters on the present flow is explained graphically. The increase in magnetic field decreases the velocity of the fluid. Also Dufour and Soret numbers enhances the temperature while they reduses the concentration field. © 2017 Published under licence by IOP Publishing Ltd.

Dual solutions of cross diffusion effects on MHD Peristaltic flow in a conduit

IOP Conference Series: Materials Science and Engineering

The aim of this study is to analyze the influence of wall flexibility and Joule heating on the peristaltic transport of a conducting nanofluid in uniform/non-uniform porous channel. The exact solutions are obtained for stream function and velocity. Further, R-K-Fehlberg integration scheme is applied to solve the energy and concentration equations. Results obtained and discussed for the flow over uniform and non-uniform geometries at different values of relevant parameters. Moreover, the trapping phenomena are investigated with the help of streamlines. Non-uniform geometry parameter, magnetic parameter, and permeability parameter have a strong impact on trapping phenomena. The fluid velocity is high in the diverging channel when compared to the uniform channel, while the situation is reversed for temperature and concentration fields. © 2017 Elsevier Ltd

Joule heating and wall flexibility effects on the peristaltic flow of magnetohydrodynamic nanofluid

Objective: In the present paper the influence of heat transfer, wall slip conditions, and wall properties on the peristaltic transport of an incompressible conducting Bingham fluid in a non-uniform porous channel is studied. Methods/Statistical Analysis: Exact analytical solutions have been obtained for the axial velocity and the temperature by using the assumptions of long wavelength and low-Reynolds number. Findings: The effects of the essential parameters on the velocity and temperature distributions are demonstrated through graphs. It is noticed that the presence of porous medium reduces the velocity and temperature in the peristaltic channel. Further, the size of the trapped bolus gets reduced due to the presence of porous medium/magnetic field whereas opposite behaviour is noticed with the increasing slip at the walls. Application/Improvements: The results reveal that the presence of magnetic field/porous medium has remarkable effect on the peristaltic transport of yield stress fluids (such as blood) which may lead to possible technological applications in designing bio- medical instruments.
