The experimental investigation was performed for votex generator jets(VGJs)controlling flow separation occurred in the suction side of low pressure turbine at low Reynolds number conditions.
研究发现,VGJs有效地控制了低雷诺数条件下叶栅吸力面的流动分离;VGJs需要一个最小有效吹气比,大于此吹气比时,VGJs效果基本上不变,高吹气比VGJs效果稍微减弱;VGJs射流偏斜角越大,控制效果越好,90°偏斜角效果最好;位置对VGJs效果影响很大,VGJs控制流动分离的最佳位置应该在分离点附近;随着雷诺数提高,VGJs效果减弱,更高的雷诺数,VGJs会增大叶片损失。
