Flow patterns and mixing rates in agitated vessels .

Mixing rates in agitated vessels are predicted through measurement of the flow patterns which determine them. These measurements suggest the use of a model that assumes that nearly all the mixing occurs in a small "perfectly mixed" region near the impeller, with flow throughout the remainder of the tank serving primarily to bring the fluid into this region of the impeller.

Modeling of gas–liquid mass transfer in a stirred tank .

A combined computational fluid dynamics (CFD) and population balance model (PBM) approach has been applied to simulate hydrodynamics and mass transfer in a 0.18 m3 gas–liquid stirred bioreactor agitated by (1) a Rushton turbine, and (2) a new pitched blade geometry with rotating cartridges. The operating conditions chosen were motivated by typical settings used for culturing mammalian cells.
