Two models are examined, one based on forces exerted by the bubble on its surroundings and the other based on energies dissipated between two successive bubble rebounds. The model is applied in the 3D Reynolds-averaged Navier-Stokes solver for the pump flow used in SIGMA RDI. The results are illustrated on the example of a mixed-flow pump impeller by comparison with the picture of the real erosion pattern and show encouraging agreement even for empirical nuclei content in the inlet flow.
