摘要

摘要: 将叶身融合技术进一步应用于涡轮,探索其技术应用效果.为此,以TTM-stage为原型,施加7种不同的叶身融合模型,并采用数值模拟方法进行了对比研究.结果表明:前缘融合面可削弱马蹄涡;侧融合面可削弱角区分离;对静叶实施融合使动叶进口总温附面层厚度降低,在通道涡作用下高总温流体被部分推离,明显降低了轮毂壁温.

Abstract: Blended blade/endwall was applied into turbine for finding out its effectiveness of application. Taking the TTM-stage as example, seven kinds of blended blade/endwall models were designed and numerically simulated and compared. The results show that:the leading edge's blending surface can weaken the horseshoe vortex; the side blending surface can weaken the corner separation; the blending surface of the vane reduces the height of the boundary layer of total temperature at the inlet of the blade, and then the passage vortex moves the fluid of high total temperature away from the hub wall, reducing the adiabatic wall temperature of the hub evidently.
