环形射流
annular jet
- 对环形射流作用下吸气流动的临界射流速度进行了全面研究。
A thorough research on the crucial velocity of sucking airflow affected by annular jet is conducted. - 设计了一种第一级能够形成环形射流的W型聚能装药，第二级采用大锥角聚能装药的串联战斗部，并且通过试验研究了该种战斗部对靶板的毁伤效果。
W type liner that can form annular jet is adopted as the forward charge and the wide Angle shaped charge is adopted as the follow through one. - 研究表明，当颗粒处于环形射流中时，颗粒的弥散速率高于气相的混合速率，小颗粒的弥散速率高于大颗粒的弥散速率，颗粒弥散受气流速比的影响较弱。
The results show that particles mix more rapidly than their gas carrier, smaller particles disperse more rapidly than larger ones, and a larger gas velocity ratio enhances particle dispersion.
