Chemically Reacting Radiative Casson Fluid Flow over a Vertical Plate in the Presence of a Heat Source/Sink and Aligned Magnetic Field

摘要

In this study, we investigated the heat and mass transfer characteristics of the MHD Casson fluid flow over a vertical plate in the presence of thermal radiation, chemical reaction and heat source/sink with buoyancy effects. The aligned magnetic field is applied along the flow direction. The governing partial differential equations are transformed as non-dimensional ODE’s using suitable transformation and resulting equations are solved using Perturbation technique. The effects of various non-dimensional governing parameters, namely thermal radiation, chemical reaction, heat source/sink, Prandtl number, Grashof number, magnetic field parameter, inclined angle parameter and slip parameter on the flow, mass and heat transfer is analyzed for both Casson and Newtonian fluid cases. Also the friction factor, the local Nusselt number and Sherwood number are discussed and presented graphically. It is found that aligned magnetic field parameter has tendency to control the flow and thermal field.
