一段摘要，急求高手人工翻译，语句可以不太专业，但不要任何在线翻译。谢谢！！译好再加20！
abstract: The current paper reports a numerical investigation of stall inception in a transonic
compressor rotor, NASA Rotor-67, by using the whole flow passages in the computations. Surface
roughness is added to one of the blades in order to trigger rotating stall. During stall inception,
the tip clearance vortex moved away from the suction surface of the roughened blade’s
upper neighbour, leading to vortex breakdown. The stall cell was found to propagate opposite
the direction of the blade rotation at about 30 per cent of rotational speed. The effect of air
bleeding on stabilizing the compressor is also studied in this work. The mean mass flowrate
removed from the bleed valves was 1.2 per cent of the mainstream flowrate. This amount of
bleeding was found to effectively suppress the stalling disturbances.
