A 1D/3D Finite-Volume coupling is proposed for the Euler/Homogeneous Equilibrium Model equations. The present approach is based on the Finite-Volume framework making it possible to tackle general equations of state. A special attention is given to the conservation of mass, momentum and energy at the common 1D/3D interface. For fluid–structure interaction induced by fast-transient phenomena occurring in pipelines, the present 1D/3D fluid coupling is also associated with a beam/shell elements coupling to deal with the mechanical pipe behavior. A series of test-cases involving both purely fluid, purely structural and coupled fluid–structure problems with available analytical or experimental references is considered to demonstrate the performance of the present 1D/3D coupling.

一维/三维有限体积耦合与梁/壳单元耦合相结合,可实现流固耦合的管道中的快速瞬变

针对欧拉/均质平衡模型方程,提出了1D / 3D有限体积耦合。本方法基于有限体积框架,可以解决一般的状态方程。特别注意在常见的1D / 3D接口处质量,动量和能量的守恒。对于管道中发生的快速瞬变现象引起的流体-结构相互作用,当前的1D / 3D流体耦合也与梁/壳单元耦合相关联,以处理机械管道行为。考虑了一系列涉及纯流体,纯结构和流固耦合问题的测试案例,并提供了可用的分析或实验参考,以证明当前的1D / 3D耦合性能。
