Abstract
The effects of heat generation and viscous dissipation on free convective flow past an impulsively started infinite vertical porous plate with Newtonian heating have been investigated. The governing boundary layer equations are solved by using an analytical technique known as Homotopy Analysis Method (HAM). The effects of heat source parameter (Q), suction parameter (s), Eckert number (Ec) and Grashof number (Gr) on the velocity and temperature fields are determined. The study revealed that the fluid temperature increases by increasing heat generation and Eckert number whereas it decreases with increasing suction velocity. The present results are compared with the exact solution results in the absence of viscous dissipation and it is found that the HAM results coincide with the exact solution results.
