RÉSUMÉ

When turbulence models are used in the simulation of a flow for which experimental results do not exist, there is as yet no reliable procedure for choosing a model or for quantifying the uncertainty of results. The present study develops an approach based on evidence theory for the resolution of these issues. The results of turbulence-model validations and of predictions using those models are fused to determine the intervals in which a flow quantity is likely to fall and a measure of confidence for each interval. The approach is tested in a subsonic flow around the RAE 2822 airfoil.
