5、Guide for the Verification and Validation of Computational Fluid Dynamics Simulations Sponsor American Institute o f Aeronautics and Astronautics Approved January 14, 1998 Abstract This document presents guidelines for assessing the credibility of modeling and simulation in computational fluid dynam
6、ics. The two main principles that are necessary for assessing credibility are verification and validation. Verification is the process of determining if a computational simulation accurately represents the conceptual model, but no claim is made of the relationship of the simulation to the real world
7、. Validation is the process of determining if a computational simulation represents the real world. This document defines a number of key terms, discusses fundamental concepts, and specifies general procedures for conducting verification and validation of computational fluid dynamics simulations. Th
8、e documents goal is to provide a foundation for the major issues and concepts in verification and validation. However, this document does not recommend standards in these areas because a number o f important issues are not yet resolved. It is hoped that the guidelines will aid in the research, devel
9、opment, and use of computational fluid dynamics simulations by establishing common terminology and methodology for verification and validation. The terminology and methodology should also be useful in other engineering and science disciplines. I Copyright American Institute of Aeronautics and Astron

18、e American Institute of Aeronautics and Astronautics (AIAA) Standards Program sponsored development of this document, Guide for the Verification and Validation of Computational Fluid Dynamics Simulations. This document originated within the AIAA Computational Fluid Dynamics Committee on Standards, w
19、hich is composed of AIAA members and others who are not affiliated with AIAA. Committee members come from industry, government, and academia, and serve voluntarily without compensation. This document represents a consensus of the Committees opinions on the terminology and methodology for verificatio
20、n and validation of computational fluid dynamics (CFD) simulations. This document is primarily a synthesis of opinions from the published literature on verification and validation in modeling and simulation. Perspectives from a wide variety of sources were assembled in order to develop the most usef
21、ul, self-consistent, and logical framework. Even though there is a variety of opinion on verification and validation in the literature, there is increasing agreement on the fundamental aspects. It is hoped that this document will promote consensus on the major issues among the CFD community at large
22、. The goal of this document is to support researchers, developers, and users of CFD by establishing common terminology and methodology for verification and validation of CFD simulations. The terminology and methodology should also be useful in other engineering and science disciplines. The AIAA Stan
