摘　　要：在管输水力瞬变过程中,管道与流体之间存在耦合互动作用,需要用流固耦合模型来进行描述。针对工程中的多相流动问题,以最常见的气液固三相流为对象,建立了考虑流固耦合效应的水力瞬变模型。通过改变流体中固相或气相的体积分数,模型可适用于气液、固液两相流以及纯液体单相流的耦合水力瞬变,是单相流耦合瞬变模型向多相流耦合瞬变模型的拓展。Fluid-structure interaction model should be used to simulate the coupling interaction effects between pipe and fluid during hydraulic transient in the pipeline.Aiming at the multiphase flow problems during engineering,the hydraulic transient model of gas-liquid-solid three phase flows with fluid-structure interaction effect is developed.By changing the volume concentration of solid or gas phase in the fluid,the proposed model can be used to simulate coupling hydraulic transient of gas-liquid,solid-liquid two-phase flows or pure liquid single-phase flows,respectively.Therefore,this model may be regarded as an extending of hydraulic transient model from single-phase flows to multiphase flows.
