The Influence of Hydrodynamic Changes in a System with a Pitched Blade Turbine on Mixing Power

Popis výsledku v původním jazyce

This paper presents an analysis of hydrodynamics in a tank with a 45 degrees and 60 degrees pitched blade turbine impeller operating while emptying the mixer and with an axial agitator working during axial pumping-down of water at different water levels above the impeller. Measurements made with the PIV method confirmed the change in direction of pumping liquid after the level dropped below the critical value, with an almost unchanged liquid stream flowing through the mixer. It was found that an increase in the value of the tangential velocity in the area of the impeller took place and the quantity of this increase depended on the angle of the blade pitch and the rotational frequency of the impeller. Change in this velocity component increased the mixing power.
