主 题:closure unsteady turbulence
摘 要:To identify ways to improve the predictive capability of the current RANS-based cavitating turbulent closure,a filter-based model(FBM)is introduced by considering sub-filter *** sub-filter stress is constructed directly by using the filter size and the conventional turbulence *** model is evaluated in steady cavitating flow over a blunt body revolution and unsteady cavitating flow around a Clark-Y hydrofoil *** with the experimental data,those results indicate that FBM can be used to improve the predictive capability considerably.
