Turbulence modelling for electronic cooling: a review

This paper is intended to provide a general review of the current capabilities of turbulence models within the specific area of electronic cooling. The work discussed in this paper is aimed at examining currently available turbulence models and the formulation of a new two-layer hybrid kε/kl model which is specifically designed for electronic application areas. A classic backward facing step configuration was used to evaluate the performance of the turbulence models in the prediction of separated flows. The preliminary results suggest that the hybrid kε/kl turbulence model is a promising zonal model to pursue.
