Effects of thermophoresis and variable suction on mixed convective heat and mass transfer flow past a vertical permeable plate in the presence of thermal radiation and uniform magnetic field

The present paper deals with the study of two-dimensional steady MHD mixed convection and mass transfer flow of an incompressible, viscous, electrically conducting fluid past an impulsively started infinite vertical porous plate in the presence of thermal radiation, large variable suction and thermophoresis. Usual similarity transformations are introduced to make non-dimensional form of the equations of momentum, energy and concentration. To obtain similarity solution of the problem, the similarity equations are solved using regular perturbation technique. Numerical results for the dimensionless velocity, temperature and concentration fields as well as for the skin-friction coefficient, wall heat transfer and particle deposition rate are obtained and displayed graphically for pertinent parameters to show physical insight and interesting aspects of the problem. Finally, a through discussion of different results is presented.
