Abstract: A subsonic compressor, a rotor blade and a method for flow stability enhancement are provided. The subsonic compressor includes a hub and a casing, a tip clearance is formed between a tip of the rotor blade and an inner wall of the casing. The tip clearance is formed as a circumferential diverging leakage passage expanding from a pressure surface side of the rotor blade of the subsonic compressor at the tip to a suction surface side of the rotor blade at the tip.
