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 experime...

Gas holdup is one of the most important hydrodynamic parameters needed for reliable design, performance estimation, and scale-up of stirred tank reactors (STRs). In the present work, local gas holdup is measured in an acrylic stirred tank reactor equipped with a Rushton impeller using X-ray computed tomography (CT) for many different operating conditions. Power consumption for different operati...
