切向喷管
... tangential inlet ==> 切线进口 tangential jet ==> 切向喷管 tangential joint ==> 切向接合 ...
旋转射流的切向速度分布相当于射流中存在一个旋转的涡核。
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。
The cycle frequency of jet fluid swing is half of that of tangential circle rotation.相应切圆呈周期性旋转,射流摆动也具有周期性,该周期是切圆旋转周期的一半。
