摘要
在对新型射流机理探讨的基础上，研究了脉冲射流喷嘴的机理和水力能量关系．得出了计算式．结果表明．脉冲喷嘴的瞬时高频射流所获能量是低频射流的２．５５８倍，是连续射流的１．４３８倍．还得出了脉冲射流喷嘴的水马力和冲击力的计算式．为脉冲射流喷嘴的应用及进一步研究，提供了理论依据．
On the basis of the investigation of advanced jet mechanism, this paper analyzes the mechanism of pulsed jet nozzle and the relstion of its power to hydraulic energy,and derives the calculation formula. The result shows that the power obtained from the instantaneous high frequency jet of pulsed nozzle to be 2. 558 times as great as that of the low-frequency jet, and 1. 438 times as great as that of continuous jet. Moreover,the calculation formulas of hydraulic power and impulsive force are derived, which presents the theoretical basis for the application and futther study of pulsed jet nozzle.
