ABSTRACT:
A theoretical analysis of free convective flow of viscous incompressible fluid through a porous medium bounded by a flat porous plate subject to periodic suction and constant heat and mass flux has been presented. The flow becomes three dimensional due to variation of suction velocity in transverse direction. Analytical expression for velocity, temperature, concentration and skin friction are obtained using perturbation technique. Numerical solutions are obtained for different values Grash of number (Gr ) ,mass Grashof number(Gc), Prandtl number (Pr),Schmidt number (Sc) and Radiation (R) .It is found that non-dimensional velocity increases with increase of Gr, Gc and Sc and decreases with increase of R ,non-dimensional temperature decreases with increasing of R, Concentration decreases with increase of Sc. and skin friction co-efficient increases with increase of Gr and R but effect of Gr is more than R.
