| 摘 要： | 采用边界元方法，对复杂的传热器件的导热规律进行了数值模拟，在控制方程的基础上，利用基本解，通过加权余量法建立内点和边界的积分方程，对边界进行剖分得到其离散化格式，通过器件边界面上的温度或热流可以计算出场内各点的温度分布，并绘制等温线．算例表明此方法有效，精度较高．

| Abstract: | In this paper,we proceed numerical simulation to the law of complicated.Thermal conduction equipment heat transfer by using boundary element method.On the basic of control equations,make use of fundamental solution and weighted residual method,we obtain the inner points and boundary points' integral equations and then obtain discrete forms after dividing the boundary.Through boundary of equipment temperature and thermal current,we can calculate the distribution of temperature in region and draw equal temperature curve.The example indicated that boundary element method is efficient and the accuracy is higher. |
