Method for Intensive Gas–Liquid Dispersion in a Stirred Tank

This article presents the results of hydrodynamics and mass exchange in a stirred tank upon introduction gas from an open vortex cavity into local liquid regions with reduced pressure. It establishes conditions for intensive dispersion gas. Velocity fields pressure behind stirrer paddles are determined by numerical simulation OpenFOAM. The content value, bubble diameters, phase surface experimentally. power criterion is calculated taking account input. experimental transfer data based on absorption atmospheric oxygen water during rotating presented. In this case, energy dissipation reaches 25 W/kg, 1000 m−1 coefficient up to 0.3·10−3 m/s. These parameters obviously higher than obtained apparatus through vorticity. advantage given method functional stability regardless how deep immersed or temperature Apparatuses allow varying across broad range values. allows establishing dependency between experimentally coefficient, dissipation, An equation calculating formulated geometric stirring
