COMPUTATION OF HEAT TRANSFER FROM IMPINGING TURBULENT JETS

Résumé

An axisymmetric jet impinging on a flat plate was simulated using a low-Reynolds number k−ε model. The accuracy of the numerical calculations was validated by comparing the predicted flow fields with experimental data for various nozzle-plate distance to jet diameter ratios (H/d) and Reynolds numbers. Heat transfer predictions for various H/d showed good agreement with experimental data in the wall jet region, and the complex behavior of heat transfer for small H/d is predicted. However, predictions in the neighborhood of the stagnation point were poor for small H/d. The results suggest that improved modelling in the equation for the dissipation rate of the turbulence kinetic energy is required.
