Filling processes are transient flow problems with time-
varying freesurface. Since the flow condition during the process
has great effect onthe quality of casting, the prediction of the
flow condition is veryimportant to the mold design. In this
paper, two- and three-dimensionalmodels are built to simulate
the filling process by combining theconserved scalar method with
the VOF method. The finite differencemethod is used to solve the
flow problems. From the computationalresults, the proposed
models require much less computing time thaneither the the
conserved scalar method or the VOF method. By comparingwith
other works, the results are also very close to theirs.
Theseresults can prove that the models are able to predict the
flow conditionof filling process correctly and efficiently.
