Mixed Convective MHD Flow of Visco-elastic Fluid Past A Vertical Infinite Plate With Mass Transfer

A theoretical analysis of mixed convective unsteady f low of a visco-elastic incompressible f luid past an accelerated infinite vertical porous plate subjected to a uniform suction has been investigated under the influence of a uniform transverse magnetic f ield. Approximate solutions for f luid velocity, temperature, concentration f ield and skin friction have been obtained by using perturbation technique. The effects of the various parameters involved in the solution have been studied. The profiles of f luid velocity and the skin friction are presented graphically to observe effects of the viscoelastic parameter.
