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。

It is found that the star_shaped nozzlejet has a shorter initial section and slower velocity attenuation along the jet centerline in the main region than the round nozzle jet.
