Electromagnetic Heat Transfer of Metal Foam Under Induction Heating
The experimental temperature control system with induction heating and liquid cooling was established to investigate the magnetic-to-thermal energy conversion mechanism and transient heat transfer characteristics of metal foam filling liquid under electromagnetic induction heating.Based on the loose coupling approach,a magnetic-thermal coupling model was established and solved using the frequency-domain for Maxwell equations and transient method for heat transfer.The distribution characteristics of electromagnetic field,heat source and temperature of metal foam filling liquid,as well as the ramping rate were studied subjected to varying the foam structure and material properties.The results showed that the electromagnetic heat transfer characteristics are closely related to the structure and material make of metal foams.
