Abstract :
An analysis has been carried out to study the effects of viscous dissipation, non-uniform heat source and sink on casson fluid flow for an unsteady inclined permeable stretching surface. Implementing similarity transformations, the governing equations are transformed to nonlinear ODEs and numerical computations are performed to solve those equations. The influence of various physical parameters on velocity, temperature and concentration distributions is illustrated graphically and the physical aspects are discussed in detail. Results indicate that temperature dependent heat source/sink plays a vital role on controlling the heat transfer however the surface-dependent heat source/sink also has notable influence on the heat transfer characteristics. Comparisons with previously published work are performed and the results are found to be in excellent agreement.
