Abstract:

开展了一种新型机匣处理扩大轴流风扇/压气机稳定裕度的试验研究。在低速风扇试验台上模拟旋转进气畸变,分析此种畸变进气条件对压气机工作性能造成的影响,并且考察一种新型机匣处理的扩稳效果。旋转进气畸变下,压升-流量特性曲线失速边界向右下偏移,压气机失速裕度明显降低。新型机匣处理在旋转进气畸变条件下对风扇/压气机有显著的扩稳效果,较小畸变转速(200,500r/min)情况下,新型机匣处理能提高压气机稳定裕度10%~20%,同时并没有带来明显的效率损失;畸变转速为800r/min情况下,机匣处理的扩稳效果相比并不明显,但可以提高压气机工作效率1%~2%。较大畸变转速情况下,畸变方向不同,机匣处理扩稳效果有所差别正向畸变时机匣处理提高压气机失速裕度3%~10%,提高效率1%左右;而反向畸变时,失速裕度均提高10%以上,甚至达到20%,但压气机效率损失在1%左右。
