Abstract
An analysis is presented to study the mixed convection in an axisymmetric stagnation flow over a vertical cylinder with arbitrary temperature variations. Numerical solutions are given for the governing momentum and energy equations Two flow regions, namely, the buoyancy-assisted and buoyancy-opposed cases are analyzed. It is observed that the friction factor and Nusselt number increase or decrease with the buoyancy force parameter depending upon which flow regime is being considered. The effect of the Prandtl number on the flow field in both the flow regimes is discussed.
