The main objective of the present paper is to study the unsteady free convection two-dimensional flow of a non-Newtonian Casson fluid with heat transfer analysis. In momentum transfer flow study is considered with suction/blowing. The heat transfer study includes the influence of viscous dissipation, internal heat generation and thermal radiation with variable thermal conductivity. The governing modeled boundary layer partial differential equations are transformed into ordinary differential equations by suitable Similarity transformations. Further resultant equations are solved numerically using Matlab 45 Solver Via shooting technique. Various velocity and temperature profiles are investigated for governing flow and heat transfer parameters such as Suction, blowing, impermeability, unsteady parameter, casson parameter, convection parameter, Pranndtl number, thermal conductivity parameter, radiation parameter, heat source/sink parameter, Eckert number etc . Also shear stress and the rate of heat transfer are studied and derived interms skin-friction co-efficient and Nusselt number. All the above investigations are displayed through graphs and the results are well in agreement with the published results. |
