摘要 本文对影响铸件/铸型界面热交换因素进行了综述,并提出了诸因素组成的框图,可供研究界面热交换以获得准确界面边界条件的参考,从而提高计算机凝固模拟精度。 The factors influencing metal/mold interfacial heat transfer have been surveyed in the present paper, the block diagram of which has also been given. It is hoped that the block diagram serve as a reference for investigation of interfavial heat transfer to obtain more correct interfacial boundary condition and therefore improve the accuracy of computer simulation of soildification.
