Finite-element developments for multiple-phase-change problems in two-dimensional models are presented for the first time. The enthalpy method is used to simulate talent heat release in conjunction with fixed-grid techniques. An unconditionally stable implicit method is used for the time integration. The effects of boundary conditions and the different phase regions on the multiple-phase-front developments are examined for numerous examples. Discussions and conclusions are appropriately addressed.
