摘要: 对全尺寸脉冲射流喷嘴进行了优选研究,得到了四种最优尺寸关系。所得最优的全尺寸脉
冲喷嘴的功率是同尺寸普通喷嘴的1.5倍。并通过冲蚀砂砖的实验研究,作了验证。

Abstract:

In order to attain the proper size matching the oscillating cavity of the full-size pulsed jet nozzle, this paper, having made an optimization of the full-size pulsed jet nozzles, obtains the four optimum matching sizes. The power of the optimum full-size pulsed jet nozzle is 1.5 times that of the ordinary ones of the same size. The washing sand brick experiments show that the above optimum study is reliable.
