Provided that a dual-purpose nozzle capable of producing alternately such a spray and a plain water jet 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 water jet 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.
计算结果表明:使用导流叶片后,高压水通过喷嘴后具有了切向速度,并形成了较为明显的旋转射流。
