Abstract: A mathematical model for mold-filling processes under
centrifugal force conditions is proposed. Computer codes for the
centrifugal mold-filling and heat transfer processes are developed using
VC++ language. The validity of the computer modeling is examined through
comparisons of numerical sample computations on the free surface
developments in a rotating cylindrical container with analytical results
and that for a partially centrifugal mold-filled titanium casting with
experiments. The comparisons between the numerical simulation results
from the same titanium mold-filling configuration but under gravity and
centrifugal conditions, respectively, show that, at a certain rotating
velocity, the alloy melt has a much stronger tendency of mold-filling
under the centrifugal condition than under the gravity.
