在美国开发的一系列标准文档中，对计算模型验证的术语和执行该验证的框架进行了很好的定义。然而，尽管已经提出了许多方法，但还没有普遍接受的执行验证的协议。本报告的研究目的是评估最近发表的一种方法的有效性和有用性，该方法提供了一种比较模拟和实验数据场的有效方法，并将实验数据中产生的不确定性纳入模型有效性评估。根据实验室间研究的标准，设计了一项国际比较活动。15个组织参与了实验室间研究，结果证明了验证方案的有效性，并对许多问题提供了反馈，包括兴趣区域的定义，模拟结果质量测量的需要以及为验证练习专门设计实验的重要性。改进的验证协议已纳入CENWorkshop协议CWA 16799: 2014。
The terminology of validation of computational models and the framework within which it should be performed has been well-defined in a series of standards documents developed in the United States. However, there is no universally accepted protocol for performing validation, although a number of approaches have been proposed. The objective of the reported study was to assess the effectiveness and usefulness of a recently published approach that provides an efficient method for comparing data fields from the simulations and experiments, and which incorporates the uncertainty arising in the experimental data in the assessment of the model validity. An international comparison exercise was designed based on the standard for Inter-Laboratory Studies. Fifteen organisations participated in the Inter-Laboratory Study and the results demonstrated the efficacy of the validation protocol and provided feedback on a number of issues, including the definition of regions of interest, the need for a measure of the quality of the simulation results and importance of designing experiments specifically for validation exercises. The refined validation protocol has been incorporated into CENWorkshop Agreement CWA 16799: 2014.
