The V-Process is one of the most exciting metal casting techniques developed recently, and it has many advantages compared to conventional casting methods. In this paper the results of the CFD modeling of mold filling process are presented. A vacuum-sealed step pattern has been used as a molding. Direct numerical simulations were conducted using a commercial CFD code (FLOW-3D software, Flow Simulations, Inc.) for the conventional gravity mold filling technique. Flow velocity, pressure and fluid fraction distributions are obtained for this casting method. The results of the numerical simulations are compared to those obtained experimentally.
