Research on Air-core Reactor Thermal Field of the Ship

A coupled magnetic-circuit-fluid-thermal finite element model is proposed for thermal analysis of dry-type air-core reactor. The magnetic field, inductance and current damping reactor are computed firstly, and then Joule heat obtained from magnetic-circuit is applied to the calculation of fluid-thermal field as heat source. The temperature field of an air-core reactor is performed without specifying convection heat transfer coefficients at its development stage. Therefore, the experimental cost of air-core reactor is decreased and the design cycle is shortened.
