    The study deals with experimental investigation of the velocity field in the impeller discharge flow in a fully baffled cylindrical mixing vessel under turbulent regime of flow of agitated liquid. Four different axial high-speed impellers were tested. Laser Doppler anemometry was used for measurement of the radial profiles of the axial component of ensemble averaged mean velocity and the axial component of RMS fluctuating velocity just below the rotating impeller. Resulting velocity profiles were expressed by means of the main flow characteristics of investigated velocity field: flow rate criterion, total flow rate criterion and energetic efficiency of all four tested axial high-speed impellers.
