这项工作涉及在均匀光滑颗粒流体动力学（SPH）框架下的流固耦合（FSI）问题的数值模拟。它结合了传输速度SPH方案，推进流体运动，以及处理结构变形的全拉格朗日SPH公式。由于流体控制方程和固体控制方程都在SPH框架下求解，耦合变得简单，因此严格满足FSI系统的动量守恒。已经执行了一个著名的FSI基准测试用例来验证建模并展示其潜力。
This work concerns numerical modeling of fluid-structure interaction (FSI) problems in a uniform smoothed particle hydrodynamics (SPH) framework. It combines a transport-velocity SPH scheme, advancing fluid motions, with a total Lagrangian SPH formulation dealing with the structure deformations. Since both fluid and solid governing equations are solved in SPH framework, while coupling becomes straightforward, the momentum conservation of the FSI system is satisfied strictly. A well-known FSI benchmark test case has been performed to validate the modeling and to demonstrate its potential.
