Abstract: Thispaperanalyzestheeffectsofradiation on unsteady hydromagnetic free convection flow and heat mass transfer past an infinite vertical plate. The flow in the fluid is induced due to uniform motion of the plate. At time the plate is linearly accelerated with a velocity in its own plane. And at the same time, plate temperature and concentration levels near the plate raised linearly with time t. Exact solutions for the dimensionless governing coupled, non-linear boundary layer partial differential equations are solved by using Laplace transformation technique. The solutions are in terms of exponential and complementary error function. The results obtained are presented graphically for both axial and transverse velocity. The numerical values of velocity fields are studied for different parameters such as Hall parameter (m), Hartmann number (M), rotation parameter (W), thermal radiation parameter (R), Schmidt number (Sc), thermal Grashof number (Gr) and mass Grashof number (Gc). An imposed rotation parameter W satisfying the transverse motion (transverse to main flow) disappears and the fluid moves in the direction of the plate only. The effect of concentration profiles and the effect of temperature profiles were also presented graphically. |
