000013977 520__ $$2eng$$aIn this paper, the suitability of Computational Fluid Dynamics (CFD) to evaluate and predict physical phenomena in lieu of experimental work in a jet impingement application is assessed. Previous experimental work looked at the effectiveness of different geometries in improving jet impingement cooling. This work was used to construct a numerical model of two of the geometries each running at three different Reynolds numbers. First a turbulence model is selected based on a simple two-dimensional axi-symmetric jet impingement case. The k-Ȧ SST model produced the most accurate results and was thus selected. The model was then used to simulate jet impingement in both a basic flatplate and a corrugated geometry. The corrugated geometry was expected to improve cooling performance. The trend was seen in the numerical results, particularly at higher velocities and at the most downstream jets. The trend replicates that of the experimental results, with negligible impact of the corrugations before the 3-4th jet.
