STAR-CCM+ Demo of Mixing with Volume of Fluid VOF

In this demo example, we show a simple VAT mixture with a paddle and we spin it up to about 240 RPM. As it spins up, a well develops within the fluid of the model. We’re using eurlerian multi-phase in this example between the air and water phases and we’re using a volume of fluid to define the sharp interface between the two phases.

In our demo we open up this model and investigate the geometry, look at the region definition, show how we can apply motion to this, show how we set up the phases, set up the phase & our actions, and also get some engineering values out of this, such as evaluating what the shaft power requirements are.
