Rushton Turbine Vortices


The Colorful Fluid Mixing Gallery



These graphics show the turbulent vortices forming behind the blades of a Rushton turbine. The vortices are visualized by means of an iso-surface of vorticity magnitude, and are colored by velocity magnitude. The vortices are shown in a 3-D view, a side view and a top view. The top view shows the vortices in a manner that is similar to the first experimental visualizations done using rotating video cameras in the 1970s.

These simulations were published in the proceedings of the 10th European Conference on Mixing, in a paper titled "The Use of Large Eddy Simulation to Study Stirred Vessel Hydrodynamics" (PDF file; 1Mb).
