Analysis of Exact Solutions of Electromagnetohydrodynamic Flow and Heat Transfer of Non-Newtonian Casson Fluid in Microchannel with Viscous Dissipation and Joule Heating

Abstract

A theoretical investigation is done to study the analytical solutions for the velocity and temperature distribution of non-Newtonian Casson fluid in microchannel associated with combined effects of electromagnetohydrodynamics forces and electrokinematics forces. Heat transfer and flow characteristic of non-newtonian Casson fluid are controlled by the combination of imposed pressure gradients, applied magnetic field, and electrokinematic forces. The interesting features of the electromagnetohydrodynamics flow along with heat transfer characteristic are examined by variation in the nondimensional physical parameter on the velocity and temperate profiles. The effect of Casson parameter on the velocity and temperature distribution has been analyzed. Variation of Nusselt number with applied magnetic field and also Casson parameter has been studied.
