Modern aeronautical design is driven by a number of factors such as evolving operational requirements, the relentless drive to reduce costs and increasingly stringent environmental constraints. These have led to the requirement to treat a range of complex turbulent flow regimes. Designers demand a fine balance between simplicity of approach and competency, and thus research has inevitably focussed upon RANS‐based turbulence modelling. This paper reviews the considerable progress of recent years in improving model proficiency for aerodynamic applications. The limitations to what can be achieved are discussed and it is suggested that some important flow regimes are beyond the RANS approach. The opportunities for the development and adoption of more advanced strategies such as hybrid RANS/LES methods are briefly examined. Copyright © 2005 John Wiley & Sons, Ltd.
