| 摘 要： | 对带有孔隙射流的某大折转角直扩压叶栅性能进行了实验研究,分析了不同位置孔隙射流对壁面静压及极限流线的影响.结果表明,孔隙射流能够改善角区流动,同时降低叶片中部损失;最佳开孔位置位于25%相对叶高处,总压损失系数相对无孔隙射流叶栅降低4.9%;孔隙位置对端壁静压的影响不大.

| Abstract: | To have a better understanding of how air injection slot position affect surface pressure and surface streamline, a detailed experimental investigation has been undertaken in a large camber angle compressor cascade with air injection slot. The result indicated that the flow condition at the corner zone was improved with air injection slot, meanwhile, the losses at midspan of blade were decreased; slot position had great effect on compressor cascade performance, the optimal slot position lay in 25 percent of... |
