Abstract

A unified approach for direct simulations of fluid flow, heat transfer, and phase changes is discussed. The method is based on writing one set of conservation equation for all phases involved, allowing arbitrary changes in material properties and adding singular terms at phase boundary to ensure that the correct boundary conditions are incorporated. This approach allows the conservation equations to ge solved on a fixed grid in a very efficient way. By explicit tracking of the phase boundary by a lower dimensional moving grid, the method is capable of producing accurate solutions for complex phase boundaries. Examples of simulations of the solidification of pure materials, binary alloys, and drops impinging on a solid surface are shown.
