Abstract
This article presents results of the numerical analysis of performance of the Venturi tube, used and applied as type of static liquid-liquid mixer. The calculations were performed for a binary acetone-benzene system of completely miscible Newtonian liquids. Several variables used to describe hydrodynamics of the Venturi were proposed. The influence of orifice location and inlet velocity on the hydrodynamics and mixing effectiveness is presented. Calculations were performed using CFD methods and the Fluent solver for 2D geometry.
