Propellers and cavitation were two flow problems that ReFRESCO was suppose to tackle since the beginning of its development. Therefore, there are several CFD features, geometry and grid-generation tricks to perform accurate and fast calculation for these type of applications in ReFRESCO. Also, several papers on Verification and Validation exercises on wetted and cavitating flow on propellers have been published. ReFRESCO community members have also participated in some workshops and projects where comparison with other codes have been done. Some illustrative results can bee shown here below.
