In this work

a fully coupled fluid flow and heat transfer model was developed to analyze molten aluminum infiltration with transient solidification and remelting through a fibrous preform in a centrifugal force field. The pressure

temperature and velocity distribution in the preform and the solid volume fraction profiles were presented for different conditions. The results show that the fibrous volume fraction and the rotational speed of equipment were very influential on transient solidification and remelting in the centrifugal force field. The length of solidification zone and its solidification rate increased with the advance of infiltration interface.An increase of rotational speed and porosity resulted in an increase of composite temperature

and a decrease of the solid volume fraction

as well as the length of solidification zone during the centrifugal casting process.
