摘要/Abstract

摘要： 实验研究三维水下超声速气体射流，重点分析气体射流初期气泡运动演化过程，对射流初期数值模拟结果做相关辅证.同时引进非圆整度概念，定量分析水下气体射流初期气泡运动及形态变化的某些规律，得到一些实验分析结果，为工程实践提供了有用的参考数据.

关键词: 水下气体射流, 气泡运动, 动量射流

Abstract: An experimental research was carried out to study three-dimensional underwater supersonic gas jets. The evolutionary process of initial bubble motion of the gas jets was analyzed, providing some comparable evidence for the results of prior numerical simulation. In addition, quantitative data of the initial bubble motion and some laws of the morphological change of the underwater gas jets by introducing the concept of non-roundness were given. This paper is presented as a useful reference for engineering practice.

Key words: underwater supersonic gas jets, bubble motion, momentum jet
