MAGNETOHYDRODYNAMIC(MHD) STAGNATION POINT FLOW AND HEAT TRANSFER OF UPPER-CONVECTED MAXWELL FLUID PAST A STRETCHING SHEET IN THE PRESENCE OF NANOPARTICLES WITH CONVECTIVE HEATING

摘要

The study scrutinizes the effect of convective heating on magnetohydrodynamic (MHD) stagnation point flow and heat transfer of upper-convectedMaxell fluid over a stretching sheet in the presence of nanoparticles. The model used in the study includes the effect of Brownian motion andthermophoresis parameters. The non-linear governing equations and their boundary conditions are initially cast into dimensionless forms by similarityvariables. The resulting system of equations is then solved numerically using fourth order Runge-Kutta method along with shooting technique.Numerical results are obtained for velocity, temperature, concentration profiles, skin friction coefficient, local Nusselt number and Sherwood number.It is found that the skin friction coefficient, the local Nusselt number and Sherwood number increase with an increase in A and and decreases as thevalues of M increase. Moreover, the local Nusselt number -0(0) and local Sherwood number -0(0) increases with an increase in Bi.
