Originální abstrakt

In this paper, a new surface tension model suitable for Volume of Fluid (VOF) model is introduced. The VOF model was designed many years ago in order to be solved by FVM. Nowadays, it is used in most of commercial CFD packages, e.g., ANSYS FLUENT, ANSYS CFX, and has the capability to simulate surface tension effects. However, when surface tension is dominant, i.e., Capillary or Weber number is low; it gives rather spurious cur-rents that can cripple a velocity field in a whole domain. In VOF, the interface between the primary and the sec-ondary phases is tracked on a fixed grid. In reality, surface tension acts as a surface force, however, here, it must be imposed as a body force into momentum equations.
