摘要
介绍了铸件凝固组织模拟的 3种方法 ,并对利用各种数值方法所取得的计算机模拟结果进行了评述。重点介绍了各模型的形核和生长的数学模型 ,同时也分析了这些数学模型所存在的问题。
Three methods of casting solidification structure simulation are introduced. And the computer simulation results obtained by means of various numerical methods are reviewed. The mathematic models of the nucleation and growth are presented emphatically and the existion problems models are analyzed. The development of the casting solidification structure simulation is forecasted.
