Abstract: Turbulent swirling flow occupies attention of numerous researchers worldwide. In this paper will be presented experimental results of the turbulent swirling flow investigation behind the centrifugal pump in a specially designed experimental test rig with transparent sections. Experiments will be conducted with the one-component LDV (laser Doppler velocimetry) system. Axial and circumferential velocity components will be measured subsequently for two various pump rotation speeds. Pump head characteristics will be also measured for both speeds. Integral parameters, as well as turbulence characteristics will be presented and discussed.
