Abstract
Investigations of attached partial cavitation are important because to prevent damages in hydrulic machinery
and to reduce the costs. As expected computational fluid dynamics (CFD) methods have been developed for more than
40 years to understand this phenomenon and to improve the machinery designs, as pumps and hydraulic turbines.
However, cavitation appears at high Reynolds numbers, so that, the traditional turbulence models Reynolds-averaged
