【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。更多还原

【Abstract】 The paper studied three-dimensional underwater supersonic gas jets.It focused on analysis of evolutionary process of initial bubble motion of the gas jets and compared numerical simulation for the secondary evidence on the initial gas jets.In addition, it quantitative analyzed initial bubble motion of the underwater gas jets and the morphological changes in some laws by introducing the concept of non-roundness.It got some experimental results which provide a useful reference data for engineering practice.更多还原
