Unsteady CFD Modelling for Electronics Cooling

Numerical simulations of the relatively low Reynolds number flow (Re= 14,200, based on channel height) in a ribbed channel are made using hybrid methods originating from the aerospace industry. Based on Reynolds- averaged Navier Stokes (RANS) and Large Eddy Simulation (LES), hybrid methods are explo...

Summary:Numerical simulations of the relatively low Reynolds number flow (Re= 14,200, based on channel height) in a ribbed channel are made using hybrid methods originating from the aerospace industry. Based on Reynolds- averaged Navier Stokes (RANS) and Large Eddy Simulation (LES), hybrid methods are explored using RANS-LES and RANS-Implicit-LES (RANS-ILES) models. Using a hybrid method with simple models we see how coarse we can make the grid and obtain reasonable heat transfer predictions for this particular case. Results from using different LES and hybrid RANS-(I)LES approaches are in better agreement than those using different RANS models..
