Verification and Validation in Computational Fluid Dynamics1
SAND2002 - 0529. Unlimited Release Printed March 2002. Verification and Validation in Computational Fluid Dynamics1 . William L. Oberkampf Validation and Uncertainty Estimation Department Timothy G. Trucano Optimization and Uncertainty Estimation Department Sandia National Laboratories P. O. Box 5800. Albuquerque, New Mexico 87185. Abstract Verification and Validation (V&V) are the primary means to assess accuracy and reliability in Computational simulations. This paper presents an extensive review of the literature in V&V in Computational Fluid dynamics (CFD), discusses methods and procedures for assessing V&V, and develops a number of extensions to existing ideas. The review of the development of V&V. terminology and methodology points out the contributions from members of the operations research, statistics, and CFD communities. Fundamental issues in V&V are addressed, such as code Verification versus solution Verification , model Validation versus solution Validation , the distinction between error and uncertainty, conceptual sources of error and uncertainty, and the relationship between Validation and prediction.
the analysis of surface-water quality and the risk assessment of underground nuclear-waste repositories. These kinds of predictions are beneficial in the development of public policy, in the preparation of safety procedures, and in the determination of legal liability. ... been pioneers in the development of methodology and procedures in ...
