| 摘 要： | 船舶CFD技术已越来越显示其"数值水池"的巨大潜力和广阔前景;CFD的不确定度分析也就成为"数值水池"实用化的技术瓶颈之一。以"量值溯源"为基础的测量不确定分析方法体系(如ISO-GUM)并不适用于数值模拟。自AIAA于1998年发布"CFD不确定度分析导则"以来,关于CFD不确定度分析的技术术语和定义已逐步取得统一。2009年ASME发布了"CFD不确定度分析标准"并成为美国标准,必将有力地推动CFD不确定度分析的广泛应用和方法统一。文中首先对AIAA和ASME方法进行了综述,重点评述了"数值计算不确定度"(numerical uncertainty)的评定方法;其后,对ITTC现有规程(2008年修订)以及最新进展进行了简要的总结。文中还对如何将CFD不确定分析与船舶CFD实际应用相结合的问题给出了初步建议。

| Abstract: | There was a consensus for the terminology and methodology for verification and validation in Computational Fluid Dynamics(V&V in CFD),however,the detailed procedure for verification is still a matter of an ongoing discussion and CFD users community are more or less confused with application of those recommended procedures.In this paper,a review of the AIAA(1998) Guidelines4] and ASME(2009) Standard6] for V&V in CFD is presented,focusing on definitions and equations for the quantitative assessment of numer... |
