英文摘要：

During the last two or three decades, computational fluid dynamics （CFD） has been widely used in the scientific research and the analysis and design of engineering systems. Especially in recent years, CFD has been playing a more and more important role in the design of aeronautical and astronautical vehicles. So many design conditions for realistic aircraft have been determined directly from the results of CFD. However, users and developers of CFD today face a critical question： How can the confidence in modeling and simulations be critically assessed？ Verification and validation （V＆V） of CFD are the primary methods for building and qualifying this confidence. In this paper, the state of the art of V＆V of CFD is reviewed. In the introduction, we first discuss the background and importance of V＆V in CFD, and then review briefly the history of V＆V. Secondly, the basic terminology and methodology of V＆V are discussed, including several fundamental concepts, the definitions and the basic processes. Section three discusses the primary processes and methods of verification, including analytic solution method, manufactured solution method and grid convergence analysis. Section four discusses the primary processes and methods of validation, including validation tier hierarchy, flow classification, and some guidelines for validation experiments. In the fifth section, several applications of verification and validation are presented, including the typical Lax problem solved by WENO scheme and our DWENO scheme, hypersonic flows over the hollow cylinder/truncated flare and sharp double cone configurations presented by P. Gnoffo, supersonic side-jet interaction for an axissymmetric body. Finally, some comments are made with respect to the development of V＆V of CFD in China： （1） the importance of flow classification research, （2） on software quality assurance, （3） on the international academic activities and successful databases, （4） on standardizing our experiment data and documents
