The Performance of the Rushton Turbine Eccentrically Positioned in a Mixing Vessel. Part I: The Qualitative CFD Analysis

A qualitative analysis of a liquid flow generated by a Rushton turbine eccentrically located in an unbaffled mixing vessel is presented in this paper. On the basis of CFD simulations the influence of the impeller position in the vessel on the flow pattern, velocity distributions and turbulence parameters are examined. Data are presented in visualisations and distribution maps created with various flow visualisation criterions. The results of this work can be used for the design and optimisation of mixing equipment applied in the industry.
