Abstract EN
The numerical predictions of the cavitating flow around two model scale propellers in uniform inflow are presented and discussed.
The simulations are carried out using a commercial CFD solver.
The homogeneous model is used and the influence of three widespread mass transfer models, on the accuracy of the numerical predictions, is evaluated.
The mass transfer models in question share the common feature of employing empirical coefficients to adjust mass transfer rate from water to vapour and back, which can affect the stability and accuracy of the predictions.
Thus, for a fair and congruent comparison, the empirical coefficients of the different mass transfer models are first properly calibrated using an optimization strategy.
The numerical results obtained, with the three different calibrated mass transfer models, are very similar to each other for two selected model scale propellers.
Nevertheless, a tendency to overestimate the cavity extension is observed, and consequently the thrust, in the most severe operational conditions, is not properly predicted.
