Evaluation of the turbulence model influence on the numerical simulation of cavitating flow with emphasis on temperature effect

Abstract

The aim of this paper is to investigate the influence of different turbulence models (κ- ε, RNG κ - ε, and SST κ -ω) on the numerical simulation of cavitating flow in thermosensitive fluid. The filter-based model and density correction method were employed to correct the turbulent viscosity of the three turbulence models. Numerical results obtained were compared to experimental ones which were conducted on the NACA0015 hydrofoil at different temperatures. The applicability of the numerical solutions of different turbulence model was studied in detail. The modified RNG κ - ε model has higher accuracy in the calculation of cavitating flow at different temperatures.
