The behavior of air in a model of a mixed-flow bowl pump has been investigated using a laser-Doppler anemometer. Velocity measurements were obtained at a number of sections within, upstream and downstream of the rotor. All three components of velocity were determined, and related to the rotating frame of reference using a computerised data acquisition method. The results provide useful data relevant to some complex problems of incompressible flow in turbomachines, including annular casing boundary layer growth.
