| 摘 要： | 本文对高速空气射流在受限约束下的动力学行为进行了实验研究.通过流动可视化揭示了高速空气射流在单筒和同心筒发射筒底部滞止、反转、而后向上绕经航行体或同心筒间隙向上喷入水中的演化过程.主要观察了单筒底部有无导流锥、同心筒三种间隙在不同压比和不同流量下的气水两相流态,并测量了航行体与发射筒的壁面压力分布.给出了航行体壁表面压力的动态变化规律,和沿轴向的分布规律. |
| 关 键 词： | 垂直发射 航行体 气体射流 |

| Abstract: | The present paper describes an experimental study on phenomenon of underwater confined high-speed gas jets.The evolvement process of gas jets being stagnated and turning over on the base of either single canister launcher or concentric canister launcher, and then flowing up into water either round vehicle or inside the annular space between two concentric cylinders is visualized using a digital camera.The observations of gas & water two phase flow pattern took place at conditions with 3 different annular ga... |
