Abstract: The conference series of Drag Prediction Workshop (DPW) are the most popular international conferences in verification and validation of CFD. The Common Research Model (CRM) is representative of the contemporary transonic commercial transport, and is the reference geometry selected by the DPW Organizing Committee from DPW Ⅳ to DPW Ⅵ. A large number of experiments and numerical simulations have been conducted in the world, reflecting the progress in the fields of CFD verification and validation up to date. This paper is organized as follows: introduces the CRM and related wind tunnel tests, outlines the basic information from DPW Ⅳ to DPW Ⅵ, the progress in the fields of CFD verification and validation is summarized, including numerical grid generation, numerical method and turbulent model, and comparison between numerical results and experimental data, gives a brief description of the optimization works related to the CRM, provides some thoughts and suggestions on CFD verification and validation.

Key words: CRM, DPW, CFD, turbulent model, wind tunnel test
