摘要
A method for controlling flow separation on a suction surface of a stator blade of an axial compressor/fan by means of micro air injection is characterized in that a stator blade of the axial compressor/fan is hollow and is formed by several two-dimensional hollow blade profiles stacked spanwisely; the blade profile is slotted to form a slotted blade profile; an inlet of a slot is at leading edge of the blade profile and an outlet is on a suction surface; when an airflow flows through a blade, a small portion of the airflow flows into the slot and then is ejected via the outlet; and the inlet of the slot exactly faces the incoming flow. The method can be used for an axial compressor or an axial fan to reduce flow loss and improve its efficiency.
