HEAT AND MASS TRANSFER ON MHD FLOW OF SECOND-GRADE FLUID THROUGH POROUS MEDIUM OVER A SEMI-INFINITE VERTICAL STRETCHING SHEET

Abstract

We have considered the MHD flow of an electrically conducting second-grade fluid through porous medium over a semi-infinite vertical stretching sheet. Thermophoresis, thermal radiation, and convective boundary conditions are taken into account. The governing equations reduced into a nondimensional form, making use of similarity transformations. The confined similarity equations are originated and solved using a shooting method together with a Runge-Kutta sixth-order system. The flow descriptions are discussed in detail through graphs and tables. The fluid velocity and temperature in the boundary-layer region become significantly higher with increasing values of the thermal radiation parameter. The chemical species concentration decreases in the presence of a thermophoretic parameter. The Nusselt number is enhanced with increasing surface convection parameter values. The rate of mass transfer increases with an increase in the thermophoretic parameter.
