摘要
利用CFD分析软件ANSYS11 CFX的用户接口编程技术,研究了CFX与三维时空中子动力学模型的耦合问题,并对压水堆稳态下局部三维流动行为和三维物理特性进行了数值模拟。结果表明,该方法能够更精确地研究堆内物理与热工水力行为复杂的关系,计算结果可为反应堆设计和运行分析提供有益的参考。
The local three-dimension flow model based on CFD method is coupled with space-time neutron kinetics model by using ANSYS-11 CFX＇s user interface program technique.The local three-dimension flow characteristics and reactor physics characteristic are simulated numerically.The results show that this method is of great value in engineering.It can be used to study the complicated relationship between thermal-hydraulic and reactor physics characteristics and can offer guidance for the reactor design and safety analysis.
