计算方法

Computational Approach

计算方法涉及众多变量，其中包括网格生成、所使用的流场求解器、边界条件、求解过程以及力和力矩的积分。通用研究模型（CRM）被用作第4、5和6届阻力预测研讨会（Drag Prediction Workshops）的几何模型。这些研讨会的结果可以在研讨会各自的网站上找到：

There are numerous variables in a computational approach, some of which include the grid generation, the flow solver used, the boundary conditions used, the solution procedure and the force and moment integration. The Common Research Model was used as the geometry for Drag Prediction Workshops 4, 5 and 6. The results from these workshops can be found on the websites for the workshops themselves:

在分析CRM数据的过程中，发现计算流体力学（CFD）几何模型与实际风洞模型几何形状存在差异。在这一发现之后，CFD几何模型被“扭转”以匹配实际风洞模型几何形状；因此，下文列出的数据将标注“原始（original）”或“扭转（twisted）”几何形状，以标明所使用的几何模型。关于这一发现以及用于匹配实际风洞模型几何形状的方法的更多信息，可以在论文AIAA-2012-0707中找到。

In the process of analyzing CRM data, the CFD geometry was found to be different from the actual wind tunnel model geometry. After this discovery, the CFD geometry was “twisted” to match the actual wind tunnel model geometry; therefore the data listed below will be labeled with “original” or “twisted” geometry to indicate which geometry was used. More information on this discovery and the method used to match the actual wind tunnel model geometry can be found in this paper, AIAA-2012-0707.
