Non-Newtonian MHD double diffusive natural convection flow and heat transfer in a crown enclosure

Abstract

Double diffusion natural convection phenomenon has gained significant attention in different fields of life for example geology, oceanography, metallurgy and astrophysics. The present disquisition is to investigate the mathematical analysis of fluid flow in a waver cavity in the presence of heated circular center of the cavity. The mass and heat transfer on MHD Casson fluid flow are the main focus of current study. The circular center of cavity is kept fixed and heated while the right and left walls of the wavy cavity are cold. The Lorentz force is also taken into consideration. The mathematical problem is governed in form of coupled partial differential equations and is solved by using well know finite element method. Flow distribution analysis is discussed in form of streamlines, isotherms and isoconcentration contour patterns. The obtained results are also represented in the form of kinetic energy, local heat, and mass fluxes. It is noted that under the increasing effect of the Casson parameter rate of heat transfer increase while the rate of mass transfer decrease.
