The unsaturated infiltration behavior of melt aluminum into the fiber cake preform under isothermal assumption is investigated numerically
and the evolution of unsaturated infiltration front is explained. The simulation results show that there exists an unsaturated infiltration zone between the saturated and dry performs
and the zone width changes continuously. Although the infiltration front with different saturation moves down in different way
the infiltration depth is proportional to the square root of infiltration time
which coincides well with the theoretical solution reported. This simulation method of unsaturated infiltration overcomes the shortcoming of the saturated infiltration assumption.
