Study of free and mixed convection heat and mass flow in real fluids through porous medium

Abstract

Between two parallel infinite porous plates, we investigated the influence of mixed convection, unsteady MHD incompressible, electrically viscous fluid flow passes through porous medium also assumed that upper plate is oscillatory with time parameter about a constant mean velocity while lower plate is stationary .The fluid motion is also subjected to a constant injection and suction through the lower and upper plates respectively in the presence of uniform magnetic field. The effect of oscillatory motion of a visco-elastic dusty fluid passes through a porous medium under the presence of magnetic field. Solid and spherical non conducting dust particles are distributed symmetrically. The approximate solutions are obtained for skin friction profile and velocity distribution for both the dust particles and dusty liquid. The heat source effect on mass transfer and heat convection on MHD flow through porous medium. It has been assumed that the motion of the plate moving with an increasing exponentially velocity with respect to constant heat and constant suction velocity under the effect of magnetic field. Different parameter such as heat source (S) effect with time on the velocity, concentration distribution, skin friction and temperature distribution have been discussed with graph. The effect of Mass and Heat transfer under the existence of transverse magnetic field for an oscillating two dimensional Micro-polar fluid flow through a moving infinite permeable plate in a porous medium. Investigate the Solutions for angular momentum, governing momentum, energy and concentration equations. Study the effect of chemical reaction, permeability parameters, velocity profiles, micro rotation profiles, wall stress coefficient and skin friction coefficient by using graph. An exact solution to the problem on unsteady MHD free convection flow of an incompressible, viscous, electrically conducting fluid through porous media past an infinite porous vertical/horizontal for non conducting moving plate.
