Since UVP is the method to take the velocity information by using ultrasound, this method is very suitable for measuring the velocity profile of opaque fluid. Oscillating pipe flow of a magnetic fluid was investigated experimentally to examine the applicability of this method to magnetic fluid flow. We used a diluted water-base magnetic fluid and the magnetic field was applied by two permanent magnets. Influence of an applied magnetic field on flow behaviors were discussed. The amplitude and phase of the oscillating velocity varied with intensity of the magnetic field, which yielded increase of the apparent viscosity.
