Resumen
WEI, Shuhuan; CHEN, Lingen y SUN, Fengrui. Constructal complex-objective optimization of electromagnet based on magnetic induction and maximum temperature difference. Rev. mex. fis. [online]. 2010, vol.56, n.3, pp.245-250. ISSN 0035-001X.
The good performance of an electromagnet requires high magnetic induction and a low temperature. A new complex-objective function reflected magnetic induction and maximum temperature difference is set up, and the electromagnet is optimized using the new complex-objective function. The optimization results show that the performance of the electromagnet is improved as the number of high thermal conductivity cooling discs inserted increases. When the performance of the electromagnet achieves its best level, the solenoid becomes longer and thinner as the number of high thermal conductivity cooling discs increases. Simultaneously, the magnetic induction becomes higher and the maximum temperature difference becomes lower. The optimized performance of the electromagnet also improves as the volume of solenoid increases; simultaneously, the magnetic induction first increases and then decreases, and the maximum temperature difference decreases all along.
