Abstract

There are inherent uncertainties and errors associated with using Computational Fluid Dynamics (CFD) to predict the flow field and there is no standard method for evaluating uncertainty in the CFD community. This paper describes an approach to validate the uncertainty in using CFD. The method will use the state of the art uncertainty analysts applied to the ke-realizable turbulence model to predict the velocity uncertainty of a backward facing step.
