An unstructured finite volume procedure for simulating flows with moving fronts Original Research Article

The correct prediction of moving fronts is of utmost importance in mold injection. Due to the complexity of the computational domains encountered in this engineering application, finite element methods (FEM) are widely used for predicting the fluid flow. The prediction of the position of the front are, however, usually done using finite differences because of local mass conservation requirements. This paper presents a finite volume method for simulating flows with moving fronts using Voronoi discretization, where the conservation principles are obeyed in solving the flow variables inside the domain as well as in the moving front. The method extends the knowledge of the classical finite volume method for structured grids to unstructured grids.
