Heat Transfer Analysis for Couple Stress Fluid over a Nonlinearly Stretching Sheet

Abstract

An investigation has presented to analyze the heat transfer in a boundary layer flow of an incompress-ible couple stress fluid over a nonlinear stretching sheet. The heat transfer problem have been analyzed for the two heating processes, 1) PST (prescribed surface temperature case) and 2) PHF (prescribed heat flux case). The governing partial differential equations for flow and heat transfer are transformed to ordinary differential equations. The numerical solutions have been obtained by using fourth order Runge-Kutta method coupled with shooting method. The effects of dimensionless surface temperature, couple stress parameteř, Prandtl number P r , Eckert number E c , non-linear stretching sheet parameter n and 1 ; ; 2 have been observed by graphical illsurations.
