Abstract
A study is reported on the heat transfer characteristics of a flat plate when an axisymmetric air jet impinges normally on to the plate. The two-dimensional Navier-Stokes equations are solved by using the kε Boussinesq Viscosity Model (BVM). Refined wall function relations are used for the evaluation of the k-equation. The turbulence Prandtl number is proposed as a function of the local ratio of turbulent energy production to energy dissipation rate. Predictions by the present model show generally good agreement with the experimental data.
