ABSTRACT: It is numerically studied the influence of the angular velocity, the
molten metal viscosity, and the mold wall roughness on the molten metal
distribution in the mold of a horizontal centrifugal casting process. The
undesirable raining phenomenon sometimes arises in horizontal centrifugal
casting. It occurs when the molten metal rains or falls from the top of the
mold to the bottom while the mold is rotating. Using Computational Fluid
Dynamics simulations, the conditions for the emergence of the raining
phenomenon were explored in this work. For the system considered, angular
velocities less than 77 rad/s cause the emergence of the raining phenomenon and
accumulation of the molten metal in the lower part of the mold, whereas angular
velocities greater than 77 rad/s produce a constant thickness of the molten
metal and prevent raining.
