Abstract
This paper presents results of measurements performed in uncovered baffled andunbaffled stirred tanks. The Laser Doppler Anemometry (LDA) set consists of a300 mW argon-ion laser generating two pairs of blue and green beams. Additionally,three turbulence models are verified to simulate mixing dynamics in uncovered baf-fled and unbaffled stirred tanks. Simulations are performed using both the steady-and the transient-state approach. The unbaffled tank was modeled using both thesingle- and the multiphase approaches. The cited correlations of the central vortexdepth are used to verify the multiphase calculations. In order to reduce the computa-tional time, a simplified numerical model is proposed. It assumes a single-phase simu-lation without the central vortex. The flow fields below the central vortex level arecompared between the single- and the multiphase approach. The simplified modelcan be used both to design and optimize the mixing process. The CFD analysis belongs to fluid mechanics analysis in the scientific discipline of Mechanical Engineering.
