| 摘 要： | 在常压下将空气通过风机送入稳定箱,稳定后的气体经过流线型组合喷嘴产生高速射流射入大气.用实验方法测试了该组合喷嘴的射流速度场.结果表明,组合射流结构分为初始段、基本段、过渡段和均匀混合段.在基本段和均匀混合段中径向速度分布存在自模性.文章给出了计算模式.并就实验中发现的射流脉冲机理进行了探讨.

| Abstract: | Compressed air was passed through a stabiliser, and the stabilized air flowedout at a high velocity through the combined streamline nozzles to produce jets. The measurement of the velocity distribution of the jet showed that the structure of combined jets included four pans: beginning section, basic section, transition section and uniformly mixed section. In the basic section and the mixed section, the dimensionless velocity distributions of the jets were similar. The mathematical expressions for the velocity distributions were given, and the mechanism of jet pulsation produced in test was discussed. |
