Chemical reaction effect on unsteady MHD flow past an impulsively started inclined plate with variable temperature and mass diffusion in the presence of hall current

The present study is carried out to examine the combined effects of hall current and chemical reaction on flow model. the model consists of unsteady flow of a viscous,incompressible and electrically conducting fluid. the flow is along an impulsively started inclined plate with variable wall temperature and mass diffusion. the magnetic field of uniform strength is applied perpendicular to the flow. the model contains equations of motion,diffusion equation and equation of energy. the governing equations involved in the present analysis are solved by the laplace-transform technique. the velocity profile is discussed with the help of graphs drawn for different parameters,like thermal grashof number,mass grashof number,prandtl number,chemical reaction parameter,hall parameter,the magnetic field parameter and schmidt number. the numerical values obtained for skin-friction were tabulated. we found that the values obtained for velocity,concentration and temperature are in concurrence with the actual flow of the fluid. © 2017 jordan journal of mechanical and industrial engineering.
