The Twisted Delft Hydrofoil and the Potsdam Propeller Test Case (PPTC) were used to analyse and compare the capabilities of Reynolds-Averaged Navier Stokes Equations simulations (RANSE simulations) and detached-eddy simulations (DES) to predict three-dimensional cavitating flow. Although the RANSE simulations were able to predict the lift and drag forces in reasonable agreement with the experiments, it has been shown that the accurate numerical simulation of cavitational flow requires the use of an advanced model such as the SST k-omega detached-eddy model.
