The performance of a low-speed axial compressor rotor for different tip clearance gap sizes, with stationary or rotating casing wall is investigated by a numerical simulation.
结果表明存在着最佳顶部间隙,原因是顶部区域吸力面边界层引起的损失由于叶顶间隙流的作用而减少,虽然存在泄漏损失,但总损失却小于无顶部间隙时的损失。

The results of the study indicate that the blade tip clearance will lead to a flow blockage at the top zone and increase the separation loss at that zone.
结果表明:动叶叶顶间隙会造成顶部区域的通流阻塞并加重顶部分离损失,根部倒角会减小根部的气流折转角,降低做功能力,而且扩大根部分离区,减小根部流量,增大根部分离损失,因此为了提高数值模拟的准确性应考虑动叶叶顶间隙和根部倒角。
