TY - JOUR TI - Power characteristics of unsteadily rotating Rushton turbine in aerated vessel AU - Woziwodzki, Szymon AU - Broniarz-Press, Lubomira TI - Power characteristics of unsteadily rotating Rushton turbine in aerated vessel AB - The paper presents an analysis of power requirements for unsteadily rotating Rushton turbine in an aerated vessel. The experiments have shown that the presence of gas phase in liquid results in reduction of power requirements. The effect of oscillation frequency on power requirements for F1 mixing mode was not observed while for FR mode power requirement was inversely proportional to oscillation frequency. The lowest relative power demand (RPD) was equal to 0.49, and the overall power requirements for unsteady mixing modes were higher in comparison to standard unidirectional mixing mode.
