Magneto Hydrodynamic Flow of Dissipative Non-Newtonian Fluid over an Exponential Stretching Surface with Thermal Radiation

Abstract

Numerical investigation is carried out to analyze the flow, heat and mass transfer behavior of magnetohydrodynamic non-Newtonian fluid (Casson) over a stretched surface with thermal radiation, chemical reaction and viscous dissipation effects. The governing PDEs are transformed as ODEs with the help of suited similarity transform. The effective Matlab package bvp5c is used to obtain the numerical solutions of the transformed equations. The impact of pertinent parameters on the common profiles (flow, temperature and concentration) is discussed in detail with the assistance of graphical illustrations for Casson and Newtonian fluid cases. Tabular results are presented to explain the nature of the wall friction, local Nusselt and Sherwood numbers.
