In this paper, a mathematical model has been developed to analyze the double diffusive convective flow of Casson fluid over an inclined stretching sheet with Cattaneo-Christov Heat Flux model. The velocity slip is considered over the surface of the stretching sheet as well. The governing equations for the pertinent model are transformed into non-dimensional highly coupled nonlinear differential equations using similarity transformations. The implicit finite difference method is used to carry out the numerical results and presented the graphs for different values of the physical parameter, Casson fluid parameter, and thermal relation time parameter, chemical reaction parameter for the cases of assisting flow, opposing flow and blowing. The present results are compared with earlier existing results and found to be very good agreement. Increasing Casson fluid parameter retards the flow velocity and temperature fields and skin friction coefficient while enhance the concentration field, rate of heat and mass transfer. The fluid velocity and temperature fields, skin friction coefficients, heat and mass transfer rates are decreased with increase in thermal relation time while concentration profile enhanced. This type of study finds applications in industry and engineering fields like condensation processes, artificial fibers and heart valves and heat conduction in tissues etc.
