tip leakage
解釋
頂部漏氣-
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。 -
Leak or leakage tip leak
泄漏葉端泄漏渦輪機 -
At the same time, tip leakage induced by pressure gradient and relative motion between the blade tip and the shroud wall is found to have a major influence on detailed flow properties in tip region of rotor passage
同時，由於轉子葉片壓力面和吸力面之間壓力梯度以及葉頂與機匣之問的相對運動產生的間隙流對轉子通道內的細微流動結構有較大的影響。 -
The numerical simulation and experimental research made on the characteristics of the clearance cavitations in kaplan turbine are described herein ; in which the analysis mainly is concentrated on the characteristics of leakage - vortex caused by the flow of the clearance between blade tip and blade chamber, that occurs at the front - pressure side of the blade, and the intensity of the secondary - flow - vortex ; furthermore, the relationship in between the leakage - vortex, secondary flow vortex, cavitations and erosion are analyzed as well
摘要對軸流轉槳式水輪機輪緣間隙流動及空化特性進行數值模擬和試驗研究，重點分析輪緣間隙流動在正面頭部泄漏流動所引起的泄漏渦帶、二次流動的漩渦強度和空化特性，以及泄漏渦帶旋轉、二次流動的漩渦與空蝕和磨損之間的關系。 -
