Marangoni boundary layer flow over a permeable surface in the presence of thermal radiation

Marangoni convection is a flow induced by the surface tension gradients associated with either thermal or concentration gradients. In this study, the problem of Marangoni boundary layer is derived in three different types of fluid over a permeable surface, where there is suction or injection effe...
