【摘要】：在既定附面層抽吸位置與抽吸量下,借助數(shù)值模擬的方法探討了計及抽吸腔室時抽吸槽道構(gòu)型對某大折轉(zhuǎn)角吸附式葉柵氣動損失以及流場結(jié)構(gòu)的影響。研究結(jié)果表明,寬槽方案可增強端區(qū)抽吸能力,改善吸附式葉柵的通流性能,同時,由于吸入進抽吸流路內(nèi)的流體速度減小,抽吸流路內(nèi)的熵增變小,總損失以及附面層抽吸功耗明顯降低。順流抽吸角度過大時,會減弱端區(qū)抽吸能力,造成通流損失增加,但計及抽吸流路影響時,適當(dāng)?shù)貙⒉鄣婪较虺騺砹骺上魅醭槲髀穬?nèi)產(chǎn)生的流動損失,進而降低總損失以及附面層抽吸功耗。
[Abstract]:The influence of suction channel configuration on the aerodynamic loss and flow field structure of a large angle adsorbed cascade was investigated by numerical simulation under the given boundary layer suction position and suction volume. The results show that the wide slot scheme can enhance the suction capacity of the end region and improve the flow performance of the adsorptive cascade. At the same time, because of the decrease of the velocity of the fluid in the suction path, the entropy increase in the suction path becomes smaller. The total loss and the power consumption of boundary layer suction are obviously reduced. When the downstream suction angle is too large, the suction capacity of the end region will be weakened and the flow loss will be increased. However, when the influence of the suction path is taken into account, the flow loss in the suction path can be weakened by properly orienting the channel towards the incoming flow. Then the total loss and the power consumption of boundary layer suction are reduced.
