Abstract

Implicit finite difference scheme has been employed to scrutinize an unsteady MHD flow past an impulsively started semi-infinite isothermal vertical plate in the presence of thermal radiation, rotation and uniform mass flux. Stability analysis is carried out using Von-Neumann technique. The numerical results for the dimensionless velocity profile, temperature profile, concentration profile are obtained by varying the representative values of the magnetic parameter M, rotation parameter, radiation parameter R, Schmidt number Sc, thermal Grashoff number Grand mass Grashoff number Gc. It is observed that rotation retards the primary and secondary velocity profiles, while local and average skin frictions are augmented by increasing the rotation parameter.
