Numerical Assessment of Cavitation Erosion for a Nozzle Flow Configuration

Paper in proceeding, 2021

The main purpose of this study is to numerically investigate and predict the cavitation erosion mechanisms in a nozzle flow configuration. To do this, an injector type geometry is numerically investigated with the open-source CFD package OpenFOAM. A compressible Euler approached is applied for two operating conditions, where results are compared with other studies from the literature. Spectral statistics and maximum surface pressure results are compared with experiments. Results show that the proposed modelling approach is capable to explain main cavitation structures that promotes erosion.
