摘要: 燃料组件的阻力特性影响堆芯不同类型组件的流量分配，对堆芯设计的影响不可忽视。为得到更为精确的燃料组件流阻特性并获得对应阻力系数，本文采用分段计算方法针对两种工质条件下的燃料组件进行了单通道三维数值模拟研究。结果表明：不同工质下，随着进口速度上升，各计算域局部压降及总压降均增大；不同工质下，对于三种形式的底板阻力系数D，四孔底板最小，圆孔底板最大，Phi孔底板介于前两者之间。最后还获得了工质分别为水和空气时燃料组件区和不同形式底板区的阻力系数，为稳态多孔介质模型中计算表征多孔介质影响的源项S提供了参考，对燃料组件通道的三维数值模拟提供了指导意义。
Abstract: The flow resistance characteristics of fuel assemblies affect the flow flux distribution of the different types of assemblies in the core, and its influence on the core design cannot be ignored. In order to obtain more accurate flow resistance characteristics and corresponding resistance coefficient of fuel assemblies, a single channel three-dimensional numerical simulation of fuel assemblies under two working fluids is carried out by using the domain division technique. The results show that with the increase of flow velocity of the inlet, the local pressure drop and total pressure drop in each calculation domain increase. Under different working fluids, for the three types of bottom plate resistance coefficient D, four holes bottom plate is the smallest, round hole bottom plate is the largest, and Phi hole bottom plate is between the first two. Meanwhile, the resistance coefficients of the fuel assembly area and different types of bottom plate areas are obtained when the working fluids are water and air respectively, which provides a reference for calculating the source term S representing the influence of porous media in the steady-state porous media model and provides a guiding significance for the three-dimensional numerical simulation of fuel assembly channels.
