  • 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.
