Magneto hydrodynamic (MHD) varied convection stream of a thick, incompressible and electrically directing liquid in a perpendicular channel is examined logically. An attractive field of uniform quality is connected opposite to the planes of the channel dividers. The liquid is followed up on by an intermittent variety of the weight angle the vertically upward way. The temperature of one of the plates is non-uniform and the temperature complexity of the dividers of the channel is adequately high to prompt warmth exchange in light of radiation. The liquid and the divert turn as one with a precise speed about the hub ordinary to the plates of the channel. An careful logical arrangement of the issue is gotten. It is found that the speed profiles decrease because of increase in either Reynolds number (or) Hartmann number (or) radiation parameter. The temperature profiles increases steadily due to either in radiation parameter concentration profiles increase because of increase in rotation parameter (or) Schmidt number (or) chemical reaction parameter.

In this paper we have studied Chemical Reaction of free convective MHD flow through vertical porous plate with variable temperature through a porous medium with heat and mass transfer. Considered the vertical plate and the medium of flow are porous. The effects of the physical parameters on the velocity, temperature, concentration, skin friction, Nusselt number have been analyzed through graphs and tables. The present study has great significance in different field of science and engineering. These flows appear in a wide variety of industrial applications and chemical process industries.

The present work is to discuss the effects of heat and mass transfer on oscillatory flow under the influence of couple stress fluid in wavy channel in the presence of chemical reaction. The effect of thermal radiation, buoyancy, chemical reaction parameter and heat source parameter on the couple stress fluid were taken into Considerations with varying temperature, concentration and slip boundary condition. The fluid is assumed to be electrically conducting in the presence of externally applied uniform magnetic field. The analytical solutions in closed form are obtained for momentem, energy and concentration equations. The effect of various parameters on the fluid velocity, temperature and concentration are analysed using graphs. The rate of heat and mass transfer coefficients at the walls are calculated.

We investigate the effect on the unsteady oscillatory flow through a vertical channel with non-uniform wall temperature. The fluid is subjected to the chemical reaction with mass transfer and the velocity slip through the porous medium is taken into consideration. Exact solutions, governing the fluid flow of the dimensionless equations are obtained and the effects of the flow parameters with substance responses and mass exchange on temperature, speed profiles, skin erosion and rate of warmth exchange are examined and appeared. It is seen that skin erosion increments on both channel plates as infusion increments on the warmth source. [ABSTRACT FROM AUTHOR]
