Sloshing Tank

Application ID: 435

Transport of large quantities of fluid can happen in unstable environments. A perfect example is an oil tanker on the high seas.

This model uses ALE for an incompressible Navier-Stokes problem with a free surface. This models the fluid with its original mesh, but allows the mesh to deform according to the fluid’s ‘deformation’. This requires that the position of the mesh and its nodes be directly coupled to the position of the fluid.

The fluid is sloshing in a 2D container. The fluid movement is driven by the fact that the gravitational vector direction is varying periodically.
