Effect of Thermal Conductivity on Magnetohydrodynamic Heat and Mass Transfer in Porous Medium Saturated with Kuvshinshiki Fluid

Abstract

The effects of Kuvshinshiki fluid on Magnetohydrodynamic (MHD) heat and mass transfer flow over a vertical porous plate with chemical reaction of nth order and thermal conductivity was carried out. The governing partial differential equations were solved numerically using implicit Crank-Nicolson method. A parametric study was performed to illustrate the impact of visco-elastic parameter, radiation parameter, thermal conductivity parameter, magnetic parameter, Prandtl number on the velocity,temperature and concentration profiles.The results were presented graphically with tabular presentations of the skin-friction,rate of heat and mass transfer which were all computed and discussed for different values of parameters of the problem. The numerical results revealed that the visco- elastic of Kuvshinshiki fluid type is growing as concentration profile increases, while the velocity and temperature profile falls ,then the radiation and thermal conductivity were growing as velocity and temperature increases. Also Sherwood number decreases as radiation increases but Sherwood number remains unchanged as thermal conductivity growing.

“…The results obtained show that for 50≤Re≤500, total Nusselt number increases with increase in Re while Re>500, there was no significant increase in Nusselt number. Idowu and Jimoh(2017) carried out the effect of kuvshinshiki fluid on Magnetohydrodynamics (MHD) heat and mass transfer flow over a vertical porous plate with chemical reaction of nth order and thermal conductivity. The results shows that the visco-elastic of kuvshinshiki fluid type is growing as concentration profile increases, while the velocity and temperature profile falls.…”
