A Unified Analysis of Solidification in Crystal Growth Process

Name of activity：

中華民國力學學會第三十屆全國力學會議

Keywords：Solidification, Crystal growth, VOF

Abstract：This simulation of multiphase solidification process can be handled by combining the VOF (Volume Of Fluid) transport equation, in which the continuum mechanics model is used to simulate the melt/solid interface and the conservation of mass, momentum, and energy. Because the melt phase, the solid phase, and the melt/solid interface are controlled by a unified control equations; if the enthalpy model based on porosity concept represents the processing of the phase transformation range, it is possible to solve the problem of phase transformation in the same way as solving the single-phase problem. Once the energy field of enthalpy for each step in time is resolved, the position of the interface can be precisely calculated with the use of VOF equation. This type of novel VOF method can be applied to find out the conditions of vertical Bridgman crystal growing located on the ground or under microgravity.
