Numerical simulation data of bubble-structure interactions in near-field underwater explosion

This data set is associated with the numerical simulation of the interactions between a high-pressure gas bubble and a thin-walled aluminum cylinder, in the context of near-field underwater explosion. The fluid dynamics is simulated using finite volume method implemented in the AERO-F solver. The structural dynamics is simulated using finite element method implemented in the AERO-S solver. The two solvers are coupled using an embedded boundary method and the FInite Volume method with Exact two-material Riemann problems (FIVER). The input files to perform this simulation are also provided. Researchers can repeat this simulation, and use it as a starting point to study related problems involving cavitation bubbles, underwater explosion, and fluid-structure interaction in general.本数据集关联于近场水下爆炸场景下高压气泡与薄壁铝圆筒相互作用的数值模拟。流体动力学过程通过搭载于AERO-F求解器的有限体积法（Finite Volume Method）完成数值模拟；结构动力学过程则通过搭载于AERO-S求解器的有限元法（Finite Element Method）完成数值模拟。两款求解器通过内嵌边界法与精确双材料黎曼问题有限体积法（FInite Volume method with Exact two-material Riemann problems，简称FIVER）实现耦合。本次模拟所需的输入文件亦随数据集一同提供，研究人员可复现该模拟过程，并以此为起点开展涉及空化气泡、水下爆炸以及通用流固耦合问题的相关研究。
