Abstract :
In the present study a Finite Difference Method has been developed to model the
transient incompressible turbulent free surface fluid flow. A single fluid has been selected for
modeling of mold filling and The SOLA VOF 3D technique was modified to increase the accuracy
of simulation of filling phenomena for shape castings. For modeling the turbulence phenomena k-?
standard model was used. In order to achieve an accurate model, solving domain was discrete to
three regions includes: laminar sub layer, boundary layer and internal region. This model was
applied to experimental models such as a driven cavity, Campbel benchmark [1] and top filled
cavity. The results show that the suggested model yield favorable predictions of turbulence flow
and have a good consistency in comparing with experimental results
