Popis:	The solid casing of an ordinary diagonal-flow fan is replaced by an. annular wing with Gdttingen 625 airfoil section in order to stabilize the unstable p-Q characteristics in low flow coefficient region. The control action with the inlet annular wing is perfect and it is possible to eliminate the unstable characteristics. In this paper, the mechanism of the passive control is investigated by means of a flow visualization with tuft from the viewpoint of-three dimensional flow fields over the rotor tip region.
