摘要
摘要本文阐述了用边界元法求解连铸机拉矫辊横截面非稳态温度场问题;推导并离散了求解二维非稳态温度场的边界积分方程;编写了计算程序;通过实验确定了边界条件。边界元法计算结果同实验结果基本吻合。
This paper deals with the problem of calculating the unsteady temperature field on cross-section of a roller in continuous casting machine by BEM. Derive and discretiSe the boundary integral equations used to solve unsteady two-dimensional temperature field. The computer programs are developed.The boundary conditions are determined by the experiment. The results calculated byBEMare identical in comparison with the results of experiment.
