DPW系列会议述评与思考

验证与确认一直是困扰计算流体力学(computational fluid dynamics, CFD)发展的关键问题.由AIAA组织的阻力预测会议(Drag Prediction Workshop, DPW)是CFD验证与确认方面的一项重要学术活动, 其宗旨是提供一个开放、公正的平台, 考核CFD方法、程序和模型的效能, 评价CFD作为应用空气动力学工具的现状.本文综述了4次DPW系列会议, 对会议的结果和结论进行了详细述评, 对其反映的一些问题进行了深入探讨. 最后根据多年对DPW的关注和研究, 提出了一些由DPW引发的思考.

REVIEW OF THE DRAG PREDICTION WORKSHOP SERIES

Verification and validation has been the key problem to the development of CFD. The AIAA CFD Drag Prediction Workshop (DPW) Series was an important academic activity concerning verification and validation of CFD, whose purpose is to provide an impartial international forum for evaluating the effectiveness of CFD Navier-Stokes solvers, and to assess state-of-the-art CFD methods as practical aerodynamic tools for the prediction of forces and moments on industry-relevant geometries. The results and conclusions of the four DPW series are summarized. Finally, some thoughts are put forward with respect to the development of CFD.
