摘要
对具有 10 6°转折角的气冷涡轮反弯叶栅进行了低速风洞实验测量和数值模拟 ,研究了叶片前缘不同位置 3排孔逆主流喷气对反弯叶片前缘马蹄涡鞍点位置和前缘再附线位置的影响 。
The experimental inve stigation of the cascade of negative bowed blades with turnin g of 106° is performed for the turbine. Influence of cooling-air inje ction from 3 rows of the leading edge holes against the mainflow is discussed on th e positions of the horseshoe saddle and the reattachment line, and th e further fundamental of energy loss increased in the cascade is presented.
