An Effect of a Baffle Length on the Power Consumption in an Agitated Vessel

An effect of the baffle length L on power consumption has been studied for an agitated vessel of inner diameter D=0.6 m equipped with short baffles. The measurements were carried out for the following agitators: Rushton and Smith turbines, pitched blade turbine (β=45°, Z=3) and propeller. Power characteristics Ne=f(Re) for different geometrical parameter L/H of the baffles were obtained within the turbulent regime of the fluid flow in the agitated vessel. The results of the experiments were approximated by means of Eq. 7, Eq. 8, Eq. 9, Eq. 10, Eq. 11, Eq. 12 and Eq. 13.
