Query: Numerical prediction of erosion due to a cavitating jet   We numerically investigate the erosion potential of a cavitating liquid jet
by means of high-resolution finite volume simulations. As thermodynamic model,
we employ a barotropic equilibrium cavitation approach, embedded into a
homogeneous mixture model. To resolve the effects of collapsing vapor
structures and to estimate the erosion potential, full compressibility is
considered. Two different operating points featuring different cavitation
intensities are investigated and their erosion potential is estimated and
compared. Different methods are used for this purpose, including collapse
detection (Mihatsch et al., 2015), maximum pressure distribution on the wall,
and a new method of generating numerical pit equivalents. The data of numerical
pit equivalents is analyzed in detail and compared with experimental data from
the literature. Furthermore, a comprehensive grid study for both operating
points is presented.
