摘　　要：为满足反应堆高精度流动传热数值仿真需求,提出了一种基于面向对象的、分层架构设计的、高可扩展的自主化反应堆计算流体动力学(CFD)软件WINGS-CFD。从理论模型、数值离散方法、软件架构等方面介绍WINGS-CFD软件的总体设计,并采用WINGS-CFD软件对反应堆典型场景流动传热工况进行了数值计算。结果表明,WINGS-CFD计算结果的精度与商用CFD软件的结果相当;WINGS-CFD软件具备优秀的并行性能,可支持亿级网格大规模数值仿真以及中子输运与流动传热耦合仿真,为反应堆系统的精细化多物理场分析提供了自主化数值技术手段。To meet the requirements of high-precision numerical simulation of reactor flow and heat transfer,this article introduces WINGS-CFD(Workbench of Intelligent Nuclear reactor desiGn and Simulation-Computational Fluid Dynamics),an autonomous Computational Fluid Dynamics(CFD)code for nuclear reactors developed by Nuclear Power Institute of China,which is designed based on the object-oriented and hierarchical architecture principles with a high degree of extension.This article comprehensively outlines the overall design concepts of WINGS-CFD,covering aspects such as theoretical models,numerical discretization methods,and code architecture.Numerical calculations for typical reactor scenarios involving flow and heat transfer conditions are conducted using WINGS-CFD.The results show that the accuracy of WINGS-CFD calculation results is equivalent to that of commercial CFD code.WINGS-CFD has excellent parallel performance,which can support large-scale numerical simulation of billions of grids and coupled simulation of neutron transport and flow and heat transfer,and provides an autonomous numerical technique for refined multi-physical field analysis of reactor system.
