A variable-density projection method for free surface flow with phase change

The development of predictive capability for free surface flow with phase change is essential to evaluate transport phenomena in aerospace, geophysical and industrial flows. This paper presents a variable-density projection method, in conjunction with Approximate-Factorization techniques (AF method) for multiphase incompressible Navier-Stokes equations. The level set method was used to capture the interface accurately. The projection method has 2 ^nd-order temporal accuracy for variable-density unsteady incompressible flows as well. This numerical investigation identifies the physics characterizing transient heat and mass transfer of multiphase free surface flow. The preliminary results show that the numerical methodology is successful in modeling the free surface with heat and mass transfer, though some severe deformation such as breaking and merging occurs.
