Abstract : A historical review is presented of the influence of computational fluid dynamics on the development of UK compressors and turbines. The ability to predict pressure distributions has led to increasingly successful attempts to tailor aerofoil shapes in such a way as to optimise performance. Once proven, new computer programs have rapidly been put to ude by Rolls-Royce and by some nonaeronautical firms. Examples are given of improvements achieved by their application. The present state of the art is assessed, and the prospects for future computational developments are discussed. The need for detailed experimental test cases is emphasized. The economical representation of viscous effects remains a key difficulty, especially when heat transfer prediction are needed.
