Abstract：In order to get the 3D turbulent flow structures in vortex pump,a test rig was set up.A special model pump was also designed.Laser Doppler Anemometry(LDA) was used to measure the velocity in volute and impeller of the pump.Three velocity components magnitudes were obtained,so was the mean square root fluctuating value.The internal flow consists of forced vortex and free vortex.Velocity distributions in volute are different from those in impeller.The liquid has been pre-swirled at the inlet of impeller.Impact loss is considerable there.Turbulent fluctuating shows isotropic characteristics.The measured data can be used to validate the numerical simulation results.
