Comparisons of Aerodynamic Loss Generated by a Squealer-Tip Turbine Rotor Blade with That by a Plane-Tip One
초록
Three-dimensional flow and aerodynamic loss in the tip-leakage flow region of a high-turning first-stage turbine rotor blade with a squealer tip have been measured with a straight miniature five-hole probe for the tip gap-to-chord ratio, h/e, of 2,0%. This squealer tip has a indent-to-chord ratio,
