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

Abstract

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 Eqs. (7)-(13).
