CFD数值模拟技术流程和参数设定是否规范与数值模拟结果的可靠性密切相关,亟待对相关内容进行标准化。上海率先展开了有关数值模拟技术标准的工作。重点介绍其中CFD部分在标准化方面的研究内容。在兼顾精度和效率的前提下,分析了部分影响数值模拟精度的主要因素。基于这些要素影响程度分析,规范了CFD数值模拟技术的标准化流程、参数设定、报告要素等内容。
CFD numerical simulation technology flow and parameter setting is closely related to the reliability of numerical simulation results, and the related content needs to be standardized. Shanghai pioneered the work on numerical simulation technology standards. Focus on which CFD part of the standardization aspects of the study. On the premise of taking both accuracy and efficiency into account, some of the main factors affecting the accuracy of numerical simulation are analyzed. Based on the analysis of the influence of these factors, the standardization process, parameter setting and reporting elements of CFD numerical simulation technology are standardized.
