This work compares a number of CFD transient models of an impinging jet with both LES and URANS models. The specific case considered is that of an impinging jet with H/D = 6 and Re 23000. The study spans over a wide number of variables for the purpose to access and directly compare different approaches. The variables tested are: turbulence model (LES Smagorinsky, standard low Reynolds k-ε and V2F), numerical discretization schemes, mesh density (total cell number and local cell distribution), synthetic turbulence inlet fluctuations. The model assessment is based on the comparison with available experiments for wall heat transfer and flow turbulent quantities. The computational cost is also considered for completeness.
