Abstract
An application of contra-rotating rotors, in which a rear rotor is in tandem with a front one and these rotors rotate in the opposite direction each other, has been proposed against a demand for developing higher specific speed axial flow pump. It is necessary to understand the internal flow behavior for higher performance design. In the present study, limiting streamlines on the blade passage walls were observed by multi-colored oil-film method at design and partial flow rates. The flow behaviors are discussed by observed results of limiting streamlines with measured results of blade-to-blade velocity distribution by Laser Doppler velocimetry and static head distributions on casing wall by pressure sensors.
