Abstract
Based on Maxwell transient electromagnetic field model and Fluent transient flow field model, the multi-physical field numerical simulation model of electromagnetic coil with water-cooled structure was established, the temperature field and flow field are calculated. In this model, the simulation results of the transient current with armature are taken as input, and the coil current distribution of the water-cooled pipeline under the action of the transient current is calculated. The cooling effect of water-cooling mode under continuous launch was analyzed and compared by coupling the wall of coil and water-cooling body directly. The results show that the temperature of the coil can be significantly controlled by water cooling, but the pressure drop of the water channel increases nonlinearly with the increase of the velocity, and the pressure drop exceed 1 MPa at 2 m/s, therefore, water pressure and structure should be taken into account in the selection of water cooling flow rate.
