Abstract The work is devoted to experimental and computational studies of the behavior of water drop in a flow behind incident shock wave and verification of calculations on this basis. High-Speed visualization of the water drop interaction with the flow behind incident shock wave was obtained in the experiments at shock wave Mach numbers Ms=1.109–1.34 and Weber numbers We = 208–2260. Conditions consistent with the experiments are simulated in the calculations. The numerical approach is based on the use of the volume of fluid (VOF) method to resolve the phase interface, large eddy simulation (LES) model to describe turbulence, and adapted dynamic grid technology. The structure of the flow near and in the wake of a drop, the features of the flow around a drop, the type of the shape evolution, and the character of the mass entrainment were studied. Comparison of simulation results with experimental data indicates good agreement with the main integral characteristics of the process, i.e. morphology, dynamics, and induction time of droplet breakup.

关于水滴与冲击波的相互作用：实验和数值模拟

摘要 该工作致力于对入射冲击波后流动中水滴的行为进行实验和计算研究，并在此基础上进行计算验证。在冲击波马赫数 Ms = 1.109-1.34 和韦伯数 We = 208-2260 的实验中，获得了水滴与入射冲击波后面流动相互作用的高速可视化。在计算中模拟与实验一致的条件。数值方法基于使用流体体积 (VOF) 方法来解析相界面、使用大涡模拟 (LES) 模型来描述湍流以及采用动态网格技术。研究了液滴附近和液滴后流动的结构、液滴周围流动的特征、形状演变的类型和质量夹带的特征。
