Modeling bubble collapse aggressiveness in traveling bubble cavitation using bubble breakup model
Original language description
The paper presents the latest progress in assessing the collapse aggressiveness of cavitation bubbles in near-steady-state flow with traveling bubble cavitation using two-way coupling of the RANS equation and the Rayleigh-Plesset equation. The aggressiveness is determined from the energy dissipated during the collapse. It is assumed that bubbles break up under suitable conditions. The criterion for bubble breakup is based on the linear Rayleigh-Taylor analysis of the spherical bubble surface. The modelis tested numerically for a 2D hydrofoil. The bubbles are assumed spherical and their interaction with the solid wall is not considered. Material effects due to cavitation erosion are not studied. The model is implemented in the in-house 3-D solver for turbulent pump flow. The numerical results for the 2D hydrofoil are compared to the erosion patterns obtained on the hydrofoil surface obtained from the cavitation tunnel measurement. Extension to complex 3D geometries, such as pump impell
