Non-similarity solutions for the boundary layer flow and heat transfer on a continuous moving wavy porous surface immersed in a quiescent electrically conducting fluid-saturated porous medium with a constant transverse magnetic field are obtained. Results for the velocity [...] and temperature O fields are presented, as well as the results for the skin-friction coefficient, C f and the local Nusselt number, Nu . These numerical results are given for different values of the amplitude of the wavy surface a, magnetic parameter M, the inverse Darcy number Da -1 , and Prandtl number Pr, then these results are illustrated graphically.
