Radiation and chemical reaction effects on MHD Casson fluid flow past a semi-infinite vertical moving porous plate

548-557A speculative investigation has been presented to explore the significant features of MHD convective Casson fluid flow past a semi-infinite moving vertical porous plate with heat source/sink are included in the flow configuration. The governing partial differential equations are remodeled into ordinary differential equations using appropriate non-dimensional variables. The ensuing differential equations are solved analytically using two term perturbation technique method. The result of flow heat and mass transfer analysis on the velocity, temperature and concentration profiles and also physical parameters like Skin friction, Nusselt number, and Sherwood numbers are shown graphically, also shown in tabular form. The results shows that Casson parameter enhances the velocity, temperature and concentration fields are decreases for increasing the values radiation and chemical reaction. Under some restriction the resultant outcome were compared with previous published results and is found in admirable agreement
