These equations describe the two-dimensional magneto-hydrodynamic pulsatile flow of a non-Newtonian fluid obeying the biviscosity model type with heat and mass transfer through a non-Darcy porous medium between two permeable parallel plates. Accordingly, the solutions of momentum, magnetic field, energy, and concentration equations were obtained. The numerical formula of the velocity, the magnetic field, the temperature, and the concentration distributions of the problem were illustrated graphically. The effects of some parameters of the problem, such as couple stress parameter a, Reynolds number Re, upper limit of apparent viscosity coefficient β, permeability parameter K, Forchheimer number Fs, magnetic-field parameter M, Prandtle number Pr, Eckert number Ec, Schmidt number Sc, Soret number Sr, and magnetic Prandtle number Rm on the flow phenomena are numerically discussed. %8 2011-04-16
