EFFECTS OF CONVECTIVE BOUNDARY CONDITIONS, RADIATION, AND HEAT TRANSFER ON MAGNETOHYDRODYNAMIC STAGNATION POINT NANOFLUID FLOW PAST A STRETCHING/SHRINKING SHEET

Abstract

A steady flow of a nanofluid stagnation point magnetohydrodynamic (MHD) over a permeable shrinking sheet with convective boundary conditions and radiation effects were explored. The governing partial differential equations were converted by using similarity transformation into a system of non-linear ordinary differential equations (ODEs). The boundary value problem solver in MATLAB software was selected to solve the ODEs. The roles of physical parameters on the skin friction coefficient and local Nusselt number as well as velocity, temperature, and nanoparticle volume fraction profiles were described in graphs and addressed in detail. Findings showed that the suction strength improved the skin friction coefficient and heat transfer rate as the sheet was shrunk. Meanwhile, the study showed that the nanoparticle volume fraction and thermal boundary layer thickness were increased in the presence of radiation.
