Oscillatory MHD Mass Transfer Channel Flow in a Rotating System with Hall Current

Abstract

The effects of heat and mass transfer on the flow of an oscillatory convective MHD channelflow of an electrically conducting viscous incompressible fluid in a slip flow regime in the presence of Hall current and thermal radiation are studied. A magnetic field of uniform strength is applied normal to the plates of channel. The two vertical porous plates of the channel are subjected to a constant injection/suction. The entire system rotates about an axis normal to the plates with a uniform angular velocity  . A closed form analytical solutions to the equations governing the fluid motion are obtained for the velocity, temperature and concentration fields. The numerical calculations for the velocity, temperature and concentration fields, and the coefficient of skin friction, rate of heat and mass transfer at the plates are performed. The results are presented graphically for different values of the physical parameters involved. It is seen that primary fluid flow is retarded due to angular velocity of the system.

Entropy Analysis in MHD Forced Convective Flow through a Circular Channel Filled with Porous Medium in the Presence of Thermal Radiation

“…Hence lot of research carried out in last two and three decades in this field. The effect of hall current and magnetic field in a oscillatory channel flow through a rotating system was depicted recently by Ahmed and Das [5]. Entropy generation in a laminar fluid flow through a circular pipe is investigated by Ahmet et al [6].…”
