Mass Transfer Effect on Unsteady Convective MHD Flow of Incompressible Fluid Past An Exponentially Accelerated Vertical Porous Plate In The Presence of Heat Source

S. Kar , N. Senapati, B.K. Swain

Abstract



The present study gives some information about the unsteady MHD flow of viscous incompressible fluid past an exponentially accelerated vertical porous plate in the presence of chemical reaction and heat source. Here a porous medium for flow domain was taken account. A transverse magnetic field is applied to the system. The fluid is considered to be optically thin and the induced hydromagnetic effects are neglected. Laplace transform technique is adopted to solve the governing equations. The numerical values of velocity, temperature, concentration and skin friction were studied. The effects of different parameters on flow field are shown through table and graphs. Also, existing results in the literature are compared with the present study as a special case. Applications of this study are shown in chemical industries, cooling reactors etc. Some important results are: heat source parameter Q acts as an aiding force for velocity. Chemical reaction helps to reduce the velocity of the fluid flow. When we provide more amount of heat, the rate of heat transfer gradually diminishes.
