This paper reports a study of mixed convection heat and mass transfer from a vertical wavy surface embedded in a homogeneous fluid-saturated porous medium using the Forchheimer flow model. The buoyancy effect is due to the variation of temperature and concentration across the boundary layer. We consider the boundary-layer regime where the Péclet number is very lager, […]. Appropriate transformations are employed to transform the governing partial differential equations into the boundary layer equations. The transformed equations have been solved numerically employing the Runge Kutta integration scheme with the shooting technique. Extensive computations are presented for a wide range of wave amplitudes the mixed convection parameter inertial parameter […] the Lewis number and the buoyancy ratio The numerical results illustrating the effects of all previously involved parameters on the velocity profiles[…] temperature […] mass […] the local Nusselt number […] and the local Sherwood number […] are presented and discussed in detail.
