Model ID: 177
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is unchanged as a function of time, as in free surface movement in a tank (no splashing) and impeller stirring, it is also possible to use the ALE (arbitrary Lagrangian-Eulerian) method.
In this model, three different regions exist initially: the oil bubble, the oil at the top of the container, and the water surrounding the bubble. This example shows you how to use the Laminar Two Phase Flow interface.
