Abstract

Similarity solution ofheat and mass transfer in a thin liquid film over amoving saturated porous medium in the presence of thermal radiation has been considered. By using shooting technique, the governing coupled nonlinear partial differential equations are transformed into coupled nonlinear ordinary differential equations in MATLAB.The flow phenomenon has been characterized with the help of obtained flow controlling parameters such asPrandtl number, Darcy number, Schmidt numberand other driving parameters. The effects of dimensionless parameters on the boundary layer velocity, temperature and concentration profiles are presented both analytically and graphically.Moreover, the physical parameters such as skin friction, local Nusselt number as well as local Sherwood number are presented both analytically and graphically.
