对包含凸台的可调静子模型进行简化,研究了不同凸台位置对端区流动的影响.通过实验测量与数值模拟对比可以发现:可调静子端区流动损失主要是由叶片气动负荷引起的泄漏及气流绕过凸台造成的掺混2个部分组成;通过合理优化设计,将凸台置于气动负荷高的叶片前缘并覆盖尽可能多的前缘间隙,能够有效降低损失,改善气动性能. The model of adjustable stator with bosses is simplified and the influence of different bosses on the flow in the end zone is studied. Comparing experimental and numerical simulations, it can be found that the flow loss in the adjustable stator end zone is mainly caused by the aerodynamic load on the blade Leakage and air flow around the bosses caused by the mixing of two parts; through the rational design, the bosses placed in the aerodynamic load of the blade leading edge and cover as much of the leading edge of the gap, can effectively reduce the loss and improve aerodynamic performance.
