摘　　要：中子物理和热工水力是堆芯两个重要的物理过程,两者的数据映射是多物理耦合分析的前提。传统数据映射方法前处理烦琐,结构化计数网格存在计数偏小的问题,本文基于开源的蒙特卡罗计算程序OpenMC和开源的计算流体力学(Computational Fluid Dynamics,CFD)程序OpenFOAM,提出基于多重网格的数据映射方法,开发了多物理耦合程序。以单棒模型对数据映射方法和耦合程序进行验证,数值模拟结果与参考文献相比,符合良好。验证结果证明了数据映射方法和所开发的耦合程序的正确性和可行性。Neutronics and thermal hydraulics are two important physical processes in the reactor,and data mapping between them is a prerequisite for multi-physical coupling analysis.Based on OpenMC,an opensource Monte Carlo computational program,and OpenFOAM,an open-source Computational Fluid Dynamics program,this paper proposes a data mapping method based on multiple grids and develops a multi-physical coupling program.The data mapping method and coupling procedure are validated by a single rod model,and the numerical simulation results good agreement with the literatures.validation results prove the validity and feasibility of the data mapping method and the coupling program developed.
