液体晃荡数值模拟研究综述

诸多工程实际应用往往会涉及到液体晃荡问题.自上世纪50年代以来,人们业已对晃荡问题进行了许多颇有成效的研究工作且取得了丰硕成果.本文仅就液体晃荡的数值研究和进展,尤其是对各类自由液面的追踪技术进行了全面的综述.就目前而言,对晃荡进行数值研究已有数种方法可供选用,但具体采用何种方法,必须根据实际问题的特点而定,因为每种方法各有其优缺点.今后的研究工作重点应针对大幅晃荡,发展更为有效的方法以便更好地模拟自由液面的翻卷、破碎及合并和计算晃荡的瞬时冲击载荷.

Numerical Simulation of Liquid Sloshing--a Review

Liquid sloshing is associated with various engineering problems. Many studies have been performed since 1950s. A comprehensive review on the study and advance of numerical simulation of liquid sloshing, with emphasis on free surface tracking techniques, has been presented in this paper. At present, several methods can be used to simulate liquid sloshing numerically. However, each method has its own advantages and disadvantages and it should be applied according to characteristics of practical engineering problems. In the future,further work should be placed on developing more effective techniques for treating very large amplitude sloshing problems, namely, for simulating overturning, breaking and merging of free surface, for predicting transient impact loads pressure of sloshing.
