Automated Optimal Design of Subsonic and Supersonic Diffusers

摘要：

Air breathing engines require a diffuser (intake) to supply the necessary airflow at the required thermodynamic conditions. The three-dimensional shape of the diffuser has a significant effect on the flow properties at the engine face (e. g. , compressor) and hence the engine performance. The aerodynamic (shape) design of the diffuser is therefore an essential element of the vehicle design. Modem Computational Fluid Dynamic (CFD) algorithms have demonstrated high accuracy in predicting diffuser flowfields, and consequently constitute an effective methodology for diffuser design. Modern automated optimization software achieves high performance diffuser designs in an efficient manner. Examples of subsonic and supersonic diffuser designs are presented.
