IMPACT OF HALL CURRENTS WITH BUOYANCY FORCES ON HYDROMAGNETIC REACTIVE CASSON FLUID FLOW PAST A SLIPPERY PLATE IN A ROTATING POROUS MEDIUM
RÉSUMÉ
This paper highlights the effects of Hall currents with buoyancy forces on an unsteady hydromagnetic free convection of a viscous incompressible electrically conducting, chemically reactive, non-Newtonian Casson fluid past a slippery vertical plate embedded in a porous medium subject to a strong magnetic field in a rotating frame. The fluid is subjected to a strong transverse magnetic field. The Casson fluid model is used to describe non-Newtonian fluid behavior. The Rosseland approximation for an optically thick fluid is used to describe the radiative heat flux in the energy equation. The Darcy model is employed to simulate drag effects in the porous medium. The governing equations are solved analytically in closed form by employing Laplace transform technique. Graphs are plotted to examine the effects of the pertinent parameters on the velocity, temperature, and concentration profiles as well as shear stresses, rate of heat, and mass transfer. The obtained results reveal that the shear stresses are significantly reduced by increasing slip parameter. The present study finds applications in magnetic material processing, electrically conducting polymer dynamics, purification of molten metals from nonmetallics, and so on.
