We have investigated effect of throughflow and gravity modulation on double diffusive convection with couple-stress fluid saturated porous media. Applying the Landau model, we derived finite amplitude in presence modulation. The a parameter produces both diminishing enhancing heat mass transfer layer. To present results used Mathematica to obtain Nusselt number Sherwood numbers numerically. Fur...
