INFLUENCE OF CRITICAL PARAMETERS OF THERMOPHOROSIS ON MHD NON-DARCY FLOW OF A CASSON FLUID PAST A PERMEABLE STRETCHING SHEET

摘要

Present investigation aims at analyzing the properties of heat and transport phenomena of thermal energy and species mass in a non-Darcy Casson fluid flow induced by a erected porous elongated surface considering the effect of non-linear radioactive heat, thermophorosis, first order chemical reaction, Newtonian heating, thermo diffusion, permeability and slip conditions. Influence of critical parameters are widely studied. By inducing the variables of similarity the basic boundary layer equations are transmuted into dimensionless equations and are resolved arithmetically using Runge – Kutta – Fehlberg shooting techniques method. The dominance of critical parameters against velocity, temperature, and concentration are explicated through graphs. Non Newtonian nature of Casson fluid is detected by observing the influence of Casson parameter on velocity, temperature, and concentration profiles. The numerical values of Skin friction coefficient, Nusselt number, and Sherwood number for different parameters are calculated and presented in tabular form.
