Abstract
The aim of this work was to extend numerical model of mould filling phenomena previously presented in [3]. Authors described some techniques for modeling single phase and free surface flows. Method, called "piston model", for modeling influence of liquid flow on gas behavior inside the mould and also, effect of local gas pressure on movement of metal free surface, was shown. In last part of this work, results from presented model were compared with data from the commercial simulation environment FLOW-3D.
