Summary:FLiNaK熔盐高温试验回路中的球床实验区旨在研究FLiNaK熔盐与燃料球的换热、腐蚀特性。石墨球床实验区采用独特的中频感应加热技术加热石墨球导体，模拟球床先进高温堆（Pebble Bed Advanced High Temperature Reactor,PB—AHTR）堆芯燃料球的释热。为了研究石墨球堆积方案对感应加热的影响，利用有限元方法对电磁感应加热进行数值模拟，获得石墨球导体的涡流损耗功率，并从涡流功率和功率分布两方面对三种石墨球堆积方案进行对比分析。结果表明：三种堆积方案的相对轴向功率分布几乎一样，每层石墨球不相切堆积方案的径向功率分布比另外两种堆积方案的径向功率分布更均匀；为了均匀加热石墨球，更好地模拟PB．AHTR堆芯燃料球释热，建议采用每层石墨球间不相切的堆积方案。

Background： The graphite pebble test section of FLiNaK molten salt high temperature testing loop was designed to study the heat transfer behavior and corrosion behavior between FLiNaK molten salt and fuel pebbles. In graphite pebble test section, the graphite pebbles are heated using a unique medium frequency inductive heating technique to simulate the heat generation inside the fuel pebbles of Pebble Bed Advanced High Temperature Reactor （PB-AHTR）. Purpose： The aim is to study the influence of the induction heating by three kinds of graphite pebbles packing scheme. Methods： Numerical simulation of induction heating using finite element method is implemented and the power loss in graphite pebbles is calculated, and then
