Technical Status Review Appraisal of the Suitability of Turbulence Models in Flow Calculations (Revue Technique - L'Evaluation de l'Applicabilite des Modeles de Turbulence dans de Calcul des Ecoulements)

Abstract

These papers provide a status review of the activities in several of the NATO nations which is aimed at assessing the use and suitability of existing, and emerging, turbulence models in flow fields calculations. Assessments are presented for both steady and unsteady flow fields associated with a variety of problems. These problems include forced convection flow fields for both attached and separated shear layers, two-phase flows, and turbulent reacting flows in addition to flow fields driven by free convection. These assessments indicate that there is presently no universal turbulence model which provides acceptable results for a broad spectrum of flow problems and some doubt is expressed concerning the possibility of ever being able to develop such a model. However, some success is noted for turbulence models which were developed for and applied to problems with similar flow field characteristics. It is generally concluded that much work remains to be done to develop a more universal turbulence model which is suitable for more general applications.
