In this work we analyse the temperature distribution in a conductor disk in transitory regime. The disk is in motion in a stationary magnetic field generated by a permanent magnet and so, the electric currents induced inside it generate heat. The system acts as a magnetic brake and is analysed using infrared sensor techniques. In addition, for the simulation and analysis of the magnetic brake, a new thermal convective matrix for the 3D Cell Method (CM) is proposed. The results of the simulation have been verified by comparing the numerical results with those obtained by the Finite Element Method (FEM) and with experimental data obtained by infrared technology. The difference between the experimental results obtained by infrared sensors and those obtained in the simulations is less than 0.0459%.
在这项工作中，我们分析了处于过渡状态的导体盘中的温度分布。该盘在由永磁体产生的恒定磁场中运动，因此，其内部感应出的电流会产生热量。该系统用作磁制动器，并使用红外传感器技术进行分析。此外，为了对磁制动器进行模拟和分析，提出了一种用于三维元胞法（CM）的新型热对流矩阵。通过将数值结果与有限元法（FEM）获得的结果以及通过红外技术获得的实验数据进行比较，验证了模拟结果。红外传感器获得的实验结果与模拟结果之间的差异小于0.0459%。
