Applications of Scaling Group of Transformation on Boundary Layer Flow and Mass Transfer Over a Stretching Sheet Embedded in a Porous Medium

Abstract

In the present paper, the boundary layer flow and mass transfer over a stretching sheet embedded in porous medium is investigated using scaling group of transformations. By the scaling group of transformations, the governing partial differential equations are transformed to the ordinary differential equations. Then those equations are solved. The analysis shows that without any adhoc assumption on the similarity solutions it can be arrived to a set of similarity solution by scaling group of transformations. Also it is found that for the increase of the permeability parameter the momentum boundary layer thickness decreases. The concentration boundary layer thickness reduces with the increasing values of the Schmidt number.
