Abstract:

On the basis of the investigation of advanced jet mechanism,this paper analyzes the mechanism of pulsed jet nozzle and the relation 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 further study of pulsed jet nozzle.

Key words: nozzle, hydraulic jet, jet drilling
