On Spectral Relaxation Approach for Thermal Diffusion and Diffusion Thermo Effects on Viscous Dissipative Casson Fluid Through a Stretched Surface

An investigation has been performed to study the influences of Soret and Dufour on steady, viscous dissipative Casson fluid flow along a linear stretching surface. Numerical solution of this problem is obtained by Spectral Relaxation Method. The outcomes are enumerated in terms of profiles of velocity, temperature, concentration, coefficients of skin friction, Nusselt and Sherwood numbers with reference to certain physical parameters. The results show that velocity reduces when there is an increase in Casson parameter. The Nusselt number enhances with Soret number whereas it decreases by enhancing Dufour number. Also, Nusselt number as well as Sherwood number increase with ratio parameter. Further, concentration profiles decrease because of increment in ratio parameter and Schmidt number, but they raise for higher Casson parameter and Soret number values.
