FVM-FEM 결합 기법을 이용한 압축성 이상 유동과 변형 가능한 구조물의 상호작용 수치해석 = Numerical simulation of deformable structure interaction with two-phase compressible flow using FVM-FEM coupling

다국어 초록 (Multilingual Abstract)

We conduct numerical simulations of the interaction of a deformable structure with two-phase compressible flow. The finite volume method (FVM) is used to simulate fluid phenomena including a shock wave, a gas bubble, and the deformation of free surface. The deformation of a floating structure is computed with the finite element method (FEM). The compressible two-phase volume of fluid (VOF) method is used for the generation and development of a cavitation bubble, and the immersed boundary method (IBM) is used to impose the effect of the structure on the fluid domain.
The result of the simulation shows the generation of a shock wave, and the expansion of the bubble.
Also, the deformation of the structure due to the hydrodynamic loading by the explosion is identified.
