模型评估方法研究是模型研发工作的重要组成部分。基于科学性验证与统计性确认提出了大气扩散CFD模型的综合确认评估方法,通过示例的方式展示了方法的使用效果。综合确认评估方法可以提高模型筛选的速度,降低统计性评估对确认性试验数据的需求量,从总体上提高模型确认的效率。评估理论的研究有助于提高基于模型的大气扩散研究的准确性,也有利于高精度模型和试验的设计、开发与遴选。
Model assessment method research is an important part of the model research and development. Based on scientific verification and statistical confirmation, a comprehensive assessment method of atmospheric diffusion CFD model is proposed, and the effect of the method is demonstrated through an example. Comprehensive validation assessment method can improve the speed of model selection, reduce the demand for statistical evaluation of confirmatory test data, and improve the efficiency of model validation. The study of assessment theory helps to improve the accuracy of model-based atmospheric diffusion studies as well as the design, development and selection of high-precision models and experiments.
