Freesurface flow calculations on an Eulerian grid
Abstract
Several methods are discussed which keep track of the location and the timeevolution of free liquid surfaces: front tracking methods. These include surface tracking methods which directly describe the free surface, and volume tracking methods which track the volume occupied by the liquid. An application of one of the latter methods (VOF) is presented, using an Eulerian approach to describe the liquid motion. In the application, spinup and spindown under lowgravity conditions of a partiallyfilled cylindrical container has been simulated. Here, surface tension effects are important; they require an accurate description of the curvature of the free surface.
