第二部分对叶顶间隙泄漏流动和叶尖涡进行了研究分析。
The second part studies and analyzes the tip leakage flow and tip vortex.
测量得到了三个不同周向位置下的涡量图和速度矢量图，并观测到了叶顶泄漏涡的涡旋结构。
The velocity vector and vortical contour in three different circumference positions were successfully acquired and the structure of the tip leakage vortex was clearly illustrated.
结果表明：叶顶间隙气流与主流发生卷吸而生成泄漏涡。
The results showed that the main flow rolled up the leakage flow of the tip clearance and generated the tip leakage vortex.
