摘要
本文较为全面地评述了国内外对具有自由液面大晃动的流固耦合问题的研究。在第2节,以两种典型的工程问题(石油化工储液罐抗震性和提离机理问题和液态金属快中子增殖堆主容器流固耦合问题)为背景全面评述了这类流固耦合问题的有关研究进展;文章的第3节较为深入讨论了这类流固耦合问题研究中所采用的分析方法(包括解析方法、半解析方法和数值方法以及问题描述的ALE格式等)和分析模型(包括位移-位移模型和多种的位移-势模型等);第4节首先从问题求解方面,说明了具有自由液面大晃动的流固耦合问题的性质和特点,然后讨论了交替求解方法及其对求解此类问题的特别适应性;最后,本文给出了这方面今后应进一步研究的问题。
In this paper, a broad review of the state of the art in the numerical methods for the fluid-structure interaction (FSI) with large free surface sloshing was provided. Based on the two engineering problems, the seismic response of the liquid storage tanks for the petrochemical engineering and the fluid-solid interaction problem of the primary container of a liquid-metal fast breeder reactor, the research progress for the numerical methods of this FSI problem was described. The solution methods and the modeling formulations for these FSI problems were reviewed. These methods are the analysis methods , semi-analysis methods, numerical methods and Arbitrary Langragian-Eule-rian (AIE) formulation to describe these programs, and the modeling formulations include the displacement-displacement formulation and several displacement-potential formulatoins. The properties and characteristics of the FSI problems with large free surface sloshing in the solution were summarized briefly, and the capabilities of the staggered solution method to the problem was discussed. In the end, a discussion of critical issues for the further research in this area was dicussed.
