摘要

本文采用实验研究了球鼻艏附近电火花气泡的运动特性，在球鼻艏正前方、斜45度和正下方不同位置通过电火花打火生成气泡，研究球鼻艏结构附近气泡脉动特性。实验发现，由于球鼻艏结构的特殊性，气泡脉动过程中呈现出与水平刚性板不同的运动状态，由于自由面的作用，气泡在离球鼻艏较近时可能会在中部产生撕裂，分成两个子气泡，随后通过总结实验，统计气泡脉动周期、射流速度、中心运动规律和分裂阈值，旨在为水下爆炸气泡运动特性研究提供参考。

Abstract

Abstract: This work experimentally studies the dynamic behaviors of spark generated bubble near ship bulbous bow with bubbles initiated in front of, under and beside (with 45 degrees from horizontal) the bulbous bow. The bubble behaviors observed are different from those in the pulsation near horizontal rigid plate. The bubble to the bulbous bow is likely to split into two sub-bubbles due to the effect of free surface. The pulsation period, jet velocity, motion of bubble center and thresholds for split are assessed through a series of experiments, which could be useful references for studies on the dynamic behavior of underwater explosion bubbles.
