摘要

为了研究压气机相似模化过程中叶顶间隙对性能的影响规律

以某燃机压气机前1.5级为对象

采用数值模拟方法

研究了不同缩尺比例压气机的性能变化规律及机理。结果表明:缩尺模化时若保持叶顶间隙尺寸不变

则压气机模型机性能会下降

导致换算的原型机峰值多变效率下降约1.4%～3.38%

压比下降约0.88%～3.17%; 叶顶间隙对流场相似性影响主要集中在叶片顶部流道区域

造成该区域流动不满足相似条件。分析流场发现

随着缩尺模化比例增加

叶顶间隙相对泄漏流量增加

叶顶流道内低速区范围扩大

泄漏涡在径向的影响范围和强度也增加

这是导致缩尺模化后流动堵塞程度加重、性能下降的主要原因

增加缩尺模化比例还会加剧叶顶泄漏流对激波的削弱。

Abstract

To reveal the effect of tip clearance on compressor performance during the scaled modeling process

the performance variation with different scaled model is numerically investigated by taking the first 1.5 stages compressor as the object. It is found that the performance of the scaled model is weakened if the tip clearance size is kept constant during the scaling process

resulting in a decrease of about 1.4%-3.38% for the peak variable efficiency and a decrease of 0.88%-3.17% for the pressure ratio of converted prototype. The influence of tip clearance on the flow field similarity is mainly concentrated in the flow passage area at the blade tip

resulting in a flow out of the similar conditions there. The flow field analysis indicates that with the increasing model shrinkage

the relative leakage flow rate of the tip clearance increases

the range of low-speed zone in the tip passage expands

and the radial influence range and intensity of leakage vortex also increase. This is the main reason for the aggravation of flow clogging and performance degradation after the scale modeling. The increasing model shrinkage ratio also facilitates weakening shock wave for the tip leakage flow.
