A Unified Analysis for Solidification in Bridgman Crystal Growth

Name of activity：

3rd international conference on smart and nanotechnology in engineering

Keywords：Solidification,Bridgman Crystal growth,Volume of Fliid(VOF)

Abstract：The 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 are controlled by a single control equation; 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 earth or under microgravity.
