| 摘 要： | 本文讨论了无限大水域中考虑液体压缩性影响下空泡溃灭冲击波对固体颗粒的作用,求得了固体颗粒所获得的最大速度;该速度的颗粒足以打坏或嵌入固壁(混凝土)中,引起更严重的空化、空蚀,形成空蚀和磨蚀的恶性循环,以致大规模剥落过流固壁面等。

| Abstract: | In this paper, the impact of shock waves of bubble collapse on solid particles in unbounded liquid is discussed by taking into account liquid compressibility. The speed of the solid particles induced by the shock waves is great enoagh to destroy or cause crack on the solid surface. The iteration of cavitation evasion and wear may caase a great qnantity of soili wall to be peeled off. |
