A Methodology for Industrial CFD

Abstract

The central tenet of this paper is that there is no fixed level of credibility or accuracy that is applicable to all CFD simulations. The required level of accuracy is dependent on the industrial context for the work. This paper describes a framework suggested by the American Institute of Aeronautics and Astronautics [1] designed to aid the assessment of the credibility of CFD simulations. The framework distinguishes between Reality, the Conceptual Model of Reality and the Computational CFD model. The processes of Qualification, Verification and Validation are used to assess the levels of Error and Uncertainty within the simulation system. The methodology presented is not exhaustive and is intended to act as a guideline for the assessment of Industrial CFD simulations.
