Numerical Prediction of Erosive Potential of Unsteady Cavitating Flow around Hydrofoil
Original language description
The paper attempts to assess the erosive potential of cavitation bubbles in unsteady flow of liquid over a prismatic hydrofoil using two-way coupling of the URANS and the Rayleigh-Plesset equations. The erosive potential is evaluated from the energy dissipated during the collapses of imploding bubbles near the hydrofoil surface. Bubble fission is modelled using a simple break-up model. The interaction between bubbles is considered by superposing the pressure change due to pressure waves generated by collapsing bubbles and propagated in the computational domain over the local pressure in the liquid. The flow is analysed using the in-house 3D solver for unsteady turbulent flow with bubble dynamics. The results are demonstrated on the NACA 2412 hydrofoilwith the incidence angle of 8 degrees and the cavitation number 1.37, which corresponds to the regime of oscillating partial cavity with periodic shedding of bubble cloud downstream of the cavity.
