Topic : Combined Effects of Radiation and Hall Current on MHD Flow past an Impulsively Started Oscillating Vertical Plate with Variable Temperature and Mass Diffusion

Authors:B. Prabhakar Reddy ||

Abstract:The numerical investigation of the effects of radiation and Hall current on an unsteady MHD flow of viscous incompressible electrically conducting fluid past an impulsively started oscillating vertical plate with variable temperature and mass diffusion has been carried out. The fluid is considered a grey, absorbing-emitting radiation but non-scattering medium. The dimensionless governing coupled partial differential equations are solved numerically by using Ritz finite element method. The influence of material parameters such as Prandtl number, Schmidt number, radiation parameter, magnetic parameter, Hall parameter, thermal and mass Grashof numbers and phase angle on the primary and secondary velocity fields, temperature and the concentration distributions are presented with the help of graphs. It has been found that an increase in the radiation parameter there is a fall in the temperature, primary and secondary velocity profiles. An increase in the value of magnetic parameter leads to decrease in the primary velocity and increase the secondary velocity. The primary and secondary velocity fields are increased when the Hall parameter increased. Further, an increase in the thermal and mass Grashof numbers increases the primary and secondary velocity fields..

Keywords: Radiation parameter, magnetic parameter, Hall parameter, oscillating vertical plate, partial differential equations.
