该研究针对AutoCFD5案例2，基于ISO 13528规范定义联合误差度量，采用Algorithm A稳健估计参与者结果离散度，将其作为CFD评分的缩放依据，以实现评分的可复现性与跨研讨会可比性。
AI 中文摘要
AutoCFD5案例2将参与者的CFD结果与风洞测量的表面压力、速度剖面及力系数进行对比。为将每次计算置于误差与计算成本的关系图中，需将这些量合并为一个数值，本文定义该数值为联合误差。遵循实验室间能力验证（ISO 13528）的规范，每个与实验的偏差均以该点参与者结果离散度的单位表示，采用标准Algorithm A稳健估计。逐点离散度按分量合并为一个尺度，使每个测量点在其分量内权重相等。联合误差是五个分量误差的固定加权和。该尺度根据2026年10月5日前收到的所有AutoCFD5提交结果计算一次后冻结，确保评分在各研讨会间可复现且可比。
英文摘要
AutoCFD5 Case 2 compares the participants' CFD results with wind tunnel measurements of surface pressure, velocity profiles and force coefficients. To place each run on a diagram of error against computational cost, these quantities must be combined into one number. This note defines that number, the joint error. Following the practice of interlaboratory proficiency testing (ISO 13528), every deviation from the experiment is expressed in units of the spread of the participants' results at that point, estimated robustly with the standard's Algorithm A. The point-wise spreads are pooled into one scale per component, so that every measurement point carries equal weight within its component. The joint error is a fixed weighted sum of five component errors. The scales are computed once from all AutoCFD5 submissions received by 5 October 2026 and then frozen, so that scores are reproducible and comparable across workshops.
