Shear Stress Effects in Cavitating Flows
Conference contribution, 2014

The current study focuses on the improvement of phase change pressure threshold estimation in the cavitating flows and its effects on the cavity characteristics. Effects of viscous shear stresses have been considered in the calculation of the tensile strength, and the liquid pocket rupturing. This method is used in the numerical simulation of the cavitating flows around the 3D Twisted Delft foil. Obtained numerical results are compared with experimental data. It is concluded that the using this medication will improve the prediction of the cavity size even in medium speed flows around foils, and propellers.
