孤立液体介质中的约束激波--一种新的侵蚀途径？
Confined Shocks inside Isolated Liquid Volumes -- A New Path of Erosion?
摘要：
激波在孤立液体体积内的独特限制放大了激波-液体相互作用的密度。我们调查这个普遍的原则，通过跨学科的研究，冲击引起的空化内液体体积，孤立在2和3维。通过结合高速可视化的理想水滴实现在微重力与平滑粒子模拟，我们证明了强大的冲击引起的空化在封闭的冲击的焦点。我们将这种分析扩展到使用分析模型对射流和液滴的地面观测，并认为由捕获激波引起的空化在高速撞击（>100 m/s）中提供了一种独特的侵蚀机制。
英文摘要：
The unique confinement of shock waves inside isolated liquid volumes amplifies the density of shock-liquid interactions. We investigate this universal principle through an interdisciplinary study of shock-induced cavitation inside liquid volumes, isolated in 2 and 3 dimensions. By combining high-speed visualizations of ideal water drops realized in microgravity with smoothed particle simulations we evidence strong shock-induced cavitation at the focus of the confined shocks. We extend this analysis to ground-observations of jets and drops using an analytic model, and argue that cavitation caused by trapped shocks offers a distinct mechanism of erosion in high-speed impacts (>100 m/s).
