Soret Effect on Mixed Convection of Casson Fluid Flow in Presence of Porous Media in a Porous Channel.

The purpose is to investigate the impact of Soret on free and mixed convective Casson fluid flow in presence of amplification in a porous channel with magnetic field is carried out analytically. The obtained are coupled PDEs are highly nonlinear and are converted to an ODEs by similarity transformation and further solved by using perturbation technique to obtain velocity, concentration and temperature equations of the physical system. The influence of non-dimensional parameters such as Prandtl number Pr, Schmidt number Sc, thermal buoyancy parameter, Reynolds number R, chemical reaction rate, concentration buoyancy parameter N, Darcy number Da, Casson fluid parameter ß, Hartmann number M2, Soret effect Sr on velocity, thickness of fluid and heat have been discussed with graphs. The few important computational outcomes reveal that the Soret effect Sr enriches the concentration, fluid flow and temperature of fluid whereas Casson fluid parameter ß diminishes the profiles. The earlier work and present work have been compared in the absence of Soret effect and is establishes to be good contract. [ABSTRACT FROM AUTHOR]
