Description: The paper is focused on evaluation the velocity profiles (circumferential and meridian distribution) downstream to the free runner. First, 3D steady turbulent flow is performed in the experimental swirl apparatus configuration. The mixing interface method is used in order to couple the non-rotating domains with runner computational domain. The computation is performed using measured value of the runner speed. Consequently, the velocity profile is obtained on survey axis displaced in convergent section. Second, the velocity profile (circumferential and meridian distribution) is measured on the test rig with LDV system at two different runner speeds. Consequently, numerical results are compared with design velocity profile [2] as well as validated against experimental data. The hydrodynamic analysis of the flow is performed in order to understand the phenomena.
