Analytical expressions of mass transfer effects on unsteady flow past an accelerated vertical porous plate with suction

This paper deals with the unsteady free convection and mass transfer boundary layer flow past accelerated infinite vertical porous flat plate with suction.  The velocity field, temperature field and concentration distribution have been solved analytically by using Homotopy analysis method. The flow phenomenon has been characterized with the help of flow parameters such as suction parameter , porosity parameter , Grashof number , Schmidt number and Prandlt number . The analytical results are presented graphically. This type of problem is significantly relevant to geophysical and astrophysical studies.
