Abstract :
The present paper analyses the effects of Hall current and heat absorption on flow model. The flow is along an exponentially accelerated vertical plate with variable heat transfer and mass diffusion. The fluid considered is viscous, incompressible and electrically conducting. The magnetic field is applied perpendicular to the plate. The problems related to rotation, Hall current, heat transfer and mass diffusion are being studied due to their applications in many processes. This is the motivation for the study of this model. Velocity profiles, temperature profiles and concentration profiles are obtained by Laplace transform technique for different parameters like rotation parameter, magnetic field parameter, heat absorption parameter, Hall parameter, acceleration parameter, Prandtl number, the angle of inclination of plate, chemical reaction parameter, acceleration parameter and time. The numerical data obtained are discussed with the help of graphs and tables. The numerical values obtained for skin-friction and Nusselt number have been tabulated.
