摘要

利用ＰＨＯＥＮＩＣＳ软件计算流场与温度场的功能，针对金属熔化与凝固过程的特点，依据单相统一控制方程，采用焓孔隙度方法，模拟了自然对流条件下相变的过程；并用经典的金属镓熔化过程基准实验进行了验证，良好的一致性表明，该程序能可靠地用于模拟金属相变过程的温度场、流场及确定相变前沿的位置。

Abstract

With the enthalpy\|porosity method and single\|phase governed equations

considering the feature of melting and solidification processes

simulation on three-dimensional transient phase transformation processes under natural convection condition is completed.All that is based on the general code PHOENICS package.The typical gallium phase transformation problem has been used for benchmar king the numerical schemes. The caculated results have been found to be fair agreement with the experimental data

so that simulation for temperature

velocity fields and the location of solid liquid interface front during phase transformation process can be proved to be reliable.
