Numerical analysis of unsteady cavitation shedding dynamics around NACA66 hydrofoil by large-eddy simulation

Abstract

Large-Eddy simulation (LES) coupling with mass transfer cavitation model was used to resolve the turbulent flow structure with cavitation. The results will focus on the cavitation shedding dynamics around NACA66 hydrofoil. The predicted results compare well with the experimental measurements for steady/unsteady partial cavitating flows. Numerical visualizations of cloud cavity evolution and surface pressure signals show relatively good agreement with the experimental data. © Published under licence by IOP Publishing Ltd.
