Provided that a dual-purpose nozzle capable of producing alternately such a spray and a plain waterjet may be provided in substitution.
但可设置能交替地产生上述喷雾及普通水柱的两用喷嘴作替代。

A new type of nozzle generating swirling-abrasive waterjet has been designed and the numerical method is employed to analyze the characteristics of the jet flow in the nozzle.
设计了一种水垫式旋转磨料射流喷嘴，并对其内部流场流动特性进行了数值研究。

Calculations showed that: with the guide vanes, the high-pressure water would have tangential velocity after it went through the nozzle and form more obvious swirling jet.
