渦旋葉片 的英文怎麼說
中文拼音 [guōxuányèpiān]
渦旋葉片
英文
swirl vane-
The vortex simulated in this article include the shedding vortex induced by the vane trailing edge boundary layer, the endwall vortex generated by the endwall boundary layer interaction, the passage vortex generated by the rotor rotation, and the leakage vortex generated by the tip clearance flow
渦輪級內的渦運動包括:導向器葉片尾緣附而層引起的脫落渦;轉子通道內轉子的旋轉運動產生的通道渦;根腳區兩個端壁附面層干涉,形成的根腳渦;存在葉尖漏流時,出現的漏流渦。Fluid flow and heat transfer characteristics in the leadingof blades at rotating state
旋轉狀態下渦輪葉片前緣的流動與換熱In this axial turbine, steam always flows along the axis of rotated axis, thus, all blades extend with the radiation shape along the axis outward
在這種軸流式渦輪機中,蒸汽總是沿主軸的旋轉軸流動的,因此,葉片由主軸向外呈輻射狀展開。The turbocharger noise is formed by the rotation noise resulting from the periodical air cutting of the fan blade and the turbulent noise of high - speed gas flows. as a continuous high frequency noise, it mainly falls between the 500 to 10 000 hz range
渦輪增壓器的噪聲是由於葉片周期性地切割空氣產生的旋轉噪聲和高速氣流形成的湍流噪聲而形成的,是一種連續性的高頻噪聲,主要分佈在500 ~ 10000hz的頻率范圍。Abstract : in order to improve the performance of a vortex classifier, a certain type of narrow plates are fitted in the passages between the blades in the rotor cage. this measure results in reduction in the cut size and increase in classifying precision. more significant effect is observed in the case of the rotor cage with fewer blades originally fitted. it is pointed out that the reason is due to the decrease in inertia counter vorticity
文摘:在渦流分級機轉籠通道中心加裝窄葉片使產品分割粒徑減小,分級精度提高.轉籠徑向葉數較少時加裝效果明顯,徑向葉片數多時效果不明顯.分析指出,這是減小了轉籠徑向葉片間慣性反旋渦強度的緣故分享友人
