  • A hot-film experimental investigation on steady boundary layer separation behaviors of the suction surface of an ultra-high-lift low-pressure turbine profile was described,which was compared with loading distribution.The experimental results indicate that the surface-mounted hot-film is a reliable indicator of the position of separation bubble and transition for the ultra-high-lift low-pressure turbine blade.In the event of lower Reynolds numbers,the size of separation bubble and transitional regime increases under declining Reynolds numbers.
