It is shown that laser anemometry, as a non-intrusive anemometer, is more suitable and convenient than traditional instruments in application to rotational flow fields, especially to the flow within centrifugal impellers which have only small width of flow passage.

研究表明在线观看国产黄AV免费看，激光測速儀作為一種先進的非接觸式測速儀器在旋轉(zhuǎn)流場特別是流道高度很小的離心旋轉(zhuǎn)流場的研究中較之傳統(tǒng)儀器更合適曰批免费视频播放、更方便www.henhenai.com。

The numerical results show that the secondary flow is enhanced in the cross section vertical to the mainstream for the revised burner, the gas tangential velocity component increases, and the rotational flow is intensified.

結(jié)果表明：改進后的燃燒器明顯地增加了垂直于主流方向截面上的二次流，氣體的切向分速度增大色玖玖视频在线观看，旋流程度增強wwwwww.日本，能夠有效地改善煤氣和空氣的混合效果。

The eddy flow around waterspout of a tub and the cyclone in the bottom of a typhoon are convergent flow-in rotational flow .

水槽排水孔形成的旋渦和臺風底層的氣旋都是Coriolis力作用下的輻合流入層旋流成年人免费黄色网站，臺風頂部是輻散流出層氣旋多人群p视频免费观看。
