Unsteady CFD modelling of turbulent flows for electronics

Abstract

Accurate thermal prediction of electronics components and systems is becoming ever more important. Here, hybrid CFD methods based on the RANS (Reynolds Averaged Navier-Stokes) and LES (Large Eddy Simulation) equations are applied to two bluff geometries to investigate the potential to make accurate thermal predictions. Originating from the aerospace industry, these models, when applied to these relatively low Reynolds number flows, agree well with experimental data and each other.
