Performance Prediction Method for Diffusing Passages with Arbitrary Shapes 921669

The paper describes a general method, based on a simplified flow model, for the analysis of compressible, unseparated and non-uniform flows in diffusing ducts of arbitrary geometry and inlet flow conditions. The method has been tested against available detailed experimental data of conical and straight rectangular diffusers, and was able to predict (with an acceptable degree of accuracy) the likely performance of diffusing flows at various values of inlet Mach numbers.
