Numerical Simulation of Induction Heating for Molten Pool Heat Transfer Experiments in Slice Geometry

摘要

Modeling results of induction heating of experimental facility developed in the frame of European IVMR project “In-Vessel Melt Retention strategy for high power nuclear reactor” have been presented. Facility is intended for heat transfer study in the stratified pool with unmixable liquid layers. Test section consists of a slice-type vessel having a semi-circular geometry representing the lower head of the reactor pressure vessel. Electrical parameters of induction heating system and design of inductor have been determined based on the modelling results to ensure the most uniform heating of the bottom layer representing heat-generating oxidic melt. A design of an electromagnetic shield has been developed to minimize electromagnetic heating of the facility vessel and influence of Lorenz forces on the natural convection of the top metal layer.
