摘要：
Turbulence modelling is a key issue to be addressed in the numerical study of violent liquid sloshing. To improve the predictive accuracy of RANS and the computational efficiency of LES, a new hybrid RANS/LES approach is developed in this paper. This model is first validated against the available experimental data for liquid sloshing in a tank without baffle. The numerical results are compared to those obtained by experiment and other three turbulence models. The performances of present hybrid method are similar with that of the classical LES model, which can provide very accurate solutions. Then, the model is employed to study liquid sloshing in a tank with a vertical baffle and a horizontal baffle. The comparisons of numerical and experimental pressure histories further confirm the capability of the present method for sloshing simulation.
