摘要
传统的气液两相流瞬态分析和管道动力响应计算是分开的,存在一定的缺陷.针对石油工业中常见的多相混输问题,介绍了常见的气液两相流瞬态模型和流固之间存在的耦合机理,在不作薄壁管假设的前提下推导出了气液两相瞬变流的流固耦合模型.与现有相似模型的对比分析表明,这一模型比较全面地考虑了流体和管道的特性以及不同的耦合形式,可以适应实验和/或仿真研究的需要.
The conventiorial analysis of the transient flow and the corresponding dynamics response of a structure in the piping system is separated, and the interaction be-tween them is often neglected. In this paper, the transient modei and the mechanism of Fluid-Structure Interaction (FSI) under the multiphase flow transportation in the oil/gas industry are introduced. A fluid-structure interaction modei for gas-liquid transient flow without shin-wall assumption is developed. Comparisons of the modei with others show that the present modei can be applied to more general cases in the experiment and/or numerical simulation.
