| 摘 要： | 介绍了国内外计算流体力学(CFD)方法在核能系统分析中应用的最新进展.CFD已经可以应用到一些三维单相瞬态流动情况中,其中包括堆芯及组件内的流场模拟,以及堆芯外空腔和其他领域的模拟分析.CFD的应用还需要进行进一步验证和基准化,并需要针对CFD的应用方法进行研究,包括建立最佳实践导则(BPG).CFD程序还被用于与热工水力系统程序的多尺度耦合以及与中子物理程序的耦合.CFD程序在两相流领域的应用还处于初级阶段,在湍流和多相流的模拟中需要更进一步发展.

| Abstract: | This paper introduces the latest international research progress of CFD application in nuclear reactor system analysis. CFD method has been applied to a few 3-D single phase transient simulations,including flow field modeling of the reactor cores, assemblies, and vessel plenums. On the other hand, CFD method applied to reactor system still needs further validation and benchmarking, meanwhile, the application of CFD also needs to be studied, including the setup of the Best Practice Guidelines (BPG). Furthermore,CFD codes are used to couple with thermal-hydraulic system codes or neutronic codes. Eventually, in two phase field and turbulence modeling, CFD codes are still being developed. |
