ANALYSIS OF VISCOUS DISSIPATION AND BUOYANCY EFFECTS OF MAGNETOHYDRODYNAMIC OF A NANOFLUID FLOW OVER A STRETCHING SHEET

Abstract

A one dimensional analysis of viscous dissipation and buoyancy effects of MHD stagnation point flow of a steady nanofluid over a stretching sheet is presented. Using some similarity transformation variables, the governing Partial differential equation representing the problem was reduced to ordinary differential equation. The transformed equations were solved using the Adomian decomposition method which results were compared with existing results in the literatures and a good agreement was observed between the present work and the existing literature. The physical parameters that occurred in the solutions such as Gasthof numbers, Lewis number, velocity ratio, Prandtl number, Eckert number were varied to determine their respective effects. It was observed that the Gasthof numbers enhances the velocity profile, Eckert number enhances the fluid temperature while Prandtl number and magnetic parameter ware observed to be a reduction agent to the fluid temperature.
