Continuous fluid is become into interruption or fluctuation pattern.There are three types of forms for pulsing jet tool：The first jet stream is in device
Exit periodically gulps down and spits, and net flow zero, this kind of jet stream is known as synthesizing jet-flow；Second of jet stream utilizes solenoid valve
It periodically opens and realization of breaking, solenoid valve is opened, jet stream outflow, solenoid valve is closed, and jet stream outflow stops；The third jet stream be
Apply a velocity fluctuation on solid jet, the third is most common pattern.
Spark-type synthesizing jet-flow is a kind of form of pulsing jet.Executing agency is spark-type synthesizing jet-flow exciter.Swash

It is unfavorable for external environment gas and is sufficient filling with excitation cavity in the backfill stage.Yang Zhenbing has invented a kind of dynamic pressure type high energy synthesizing jet-flow
Exciter (application number：201010502479.0), increase to fill out in cavity rapidly using kinetic energy possessed by external high speed incoming and be situated between
Matter makes medium in exciter cavity quickly denseization.It is far longer than the external world since spark-type electric discharge generates raw instantaneous high pressure,
And the flow resistance mouth that is pressed into driven much smaller than fluid in outfield enters cavity and from jet stream between dynamic pressure import and jet exit
The flow resistance of outlet can not cause so the device generates partial high pressure using external high speed incoming near dynamic pressure import
Dynamic pressure import half-duplex channel, the instead presence of dynamic pressure import reduce spark hair since pressure leakages are too fast and holes is apart from each other
The efficiency of raw device.
