Resumen:
The Piecewise-Linear Interface Calculation (PLIC) algorithm is a well known techniquefor interface reconstruction, widely used in several Volume of Fluid (VOF) codes both commercial andopen-source. In this work, an unstructured mesh implementation of these tools in OpenFOAM(R) isdescribed and tested. The underlying numerical features of this new solver are described, showing howthe programmed schemes accomplish local and global conservativeness. An extension of geometricalschemes to the momentum equation is also discussed, remarking the advantages of using the so calledmomentum-conserving scheme instead of a standard algebraic TVD advection method. Several bench-mark problems are solved, comparing the results with the ones available in literature and analyticalsolutions. Different error norms are used to evaluate the solver accuracy in problems involving advectionof discontinuous functions. Finally, a simple atomization problem is solved, comparing these resultswith solutions obtained using original OpenFOAM(R) VOF formulation.
