EFFECT OF THERMAL RADIATION ON FREE CONVECTION FLOW AND HEAT TRANSFER OVER A TRUNCATED CONE IN THE PRESENCE OF PRESSURE WORK AND HEAT GENERATION/ABSORPTION

ABSTRACT
Effect of heat generation or absorption and thermal radiation on free convection flow and heat transfer over a truncated cone in the presence of pressure work is considered. The governing boundary layer equations are reduced to non-similarity boundary layer equations and solved numerically by using Mathematica technique. Comparisons with previously published work on special cases of the problem are performed and the results are found to be in excellent agreement. The solutions are presented in terms of local skin friction, local Nusselt number, velocity and temperature profiles for values of Prandtl number, pressure work parameter, radiation parameter and heat generation or absorption parameter.
