Water and air in a Spinning Bowl

back to menu


This case comes from an example from the fluent Tutorial. It explained how to compute a Free Surface Flow with Fluent using the V.O.F. ( Volume Of Fluid ) algorythm. It represents the volume air fraction at different time steps. The case presented is a bowl animated with a swirl velocity. The files required can be obtained in

The results below represents the propagation of the free surface at different time steps. In fact it's the air volume fraction. The time step must be chosen cleverly to be enough little to prevent the code form exploding and enough big to make the simulation go faster. We chose a time step of 0.01 and the results are taken each 50 time steps.

We used the same time step and took the solutions every 10 time steps. The results shows the air volume fraction through the iterations.
