Abstract

Unsteady laminar free convection flow past a vertical cone with non-uniform surface heat flux varying as a power function of the distance from the apex of the cone ( x = 0 ) under viscous dissipation effect is presented here. Here is the exponent in power law variation of the surface heat flux and a is a constant. The unsteady, coupled and non-linear dimensionless partial differential governing equations of the flow are solved using a Network Simulation Method. The effect of viscous dissipation with various parameters Prandtl number , and the exponent for the velocity and temperature profiles have been studied and are analyzed graphically. The local as well as average skin-friction and Nusselt number are also analyzed graphically. The present results are compared with available results in literature and are found to be in excellent agreement.
