Abstract
AbstractPower input data are presented for a twin flat disk up‐and‐down moving (vibromixer) impeller operating in a small vessel with a range of Newtonian liquids. Vibromixer power number and Reynolds number are defined and are used to establish the Newtonian power curve for this type of mixer. Drop size distributions are presented for xylene‐in‐water dispersions under turbulent flow conditions in the vibromixer and are shown to vary with the maximum velocity of the disk (2πAf). The Sauter mean drop diameter of the distribution is related to the vibromixer Weber number, (We =ρ(2πAf)2D/σ), by an equation of the type d32/D = C (We)−3/5 with the coefficient C = 0.37.
