摘    要:叶片前缘逆主流喷射冷气使得吸力边或压力边附近出现明显的多射流卵型涡复合涡系。随距喷射点距离的增加,冷气射流与主流的掺混加强,涡系强度减弱,沿叶高分布变得均匀。压力梯度及通道涡对锅系的发展也有一定的影响。

关 键 词:气冷涡轮 流场结构 卵型涡 叶栅 燃气轮机 叶片

Abstract:A multi jet kidney shaped vortex system appeared on the suction or pressure side apparently by the coolant air that injected against the main stream. With increasing distance from the injection site, the mixing process between coolant air and main stream become more and more strong, while the vortex system was weakened, and its distribution become uniform along the whole span. The development of vortex system was affected by pressure gradient and passage vortex considerably.
Keywords:Cooled turbine  flow structure  experimental study  kidney shaped vortex
