Abstract

The problem of cooling of a heated plate by an axisymmetric isothermal fully developed turbulent jet has been numerically studied. We have performed our computations with the normal velocity relaxation turbulence model (v2 - f model) and local heat transfer coefficient predictions are compared with the available experimental data. For comparison, computations have also been carried out with the widely used k - ε model, v2 - f heat transfer predictions are in excellent agreement with the experiments, whereas the k - e model, in general, does not properly resolve the flow features, highly over-predicts the rate of heat transfer and yields physically unrealistic behaviors.
