摘要
在三维涡流区域的表面上,可引入一个入端阻抗关联矩阵以表征各离散单元上的位函数与其法向导数的关系。应用这个矩阵及罗仑兹规范,在T-Ω描述中涡流区与非导电区的分界面条件可化为非导电区的边界条件,从而可以单独求解。按此方法得出的计算结果与标准的半立方体涡流实验数据进行核对,证明结果是满意的。
An incident impedance matrix is suggested by the authors which interrelates the potential function and its first derivative to the outward normal on the surface of eddy current reigon in discreted form. By means of it and together with the Lorentz gauge, the interface conditions between the conductor and non-conductive region can be transformed into boundary conditions for the field in non-conductive region. Thus the labour of calculation is reduced. The result is verified by the data of wellknown bath-cube experiment.
