Abstract: In this research work, similarity solution of heat and mass transfer for the falling film flow on a porous medium in presence of heat generation or absorption has been modeled by Darcy-Brinkman equations and solved by using similarity technique. Heat generation, thermal radiation and chemical reaction effects are considered. By using appropriate transformations, the governing nonlinear partial equations are transformed into coupled nonlinear ordinary differential equations. Graphs are decorated to explore the influence of physical parameters on the non-dimensional velocity, temperature and concentration distributions. The local Nusselt number and the local Sherwood number are computed and analyzed numerically.

Key words: similarity solution, heat generation, absorption, falling film, porous medium
