Diffurso design
 

Hi.

Does anyone have any references to how a diffusor should be designed, i.e. angles vs. velocity. My "diffusor problem" has air as fluid and an inlet/outlet velocity approx. 20m/s - 5m/s. I would like to avoid any detachment.

And, does anyone know if a diffusor flow is inherently unsteady?

Any references to papers or books are welcome.

see "Diffuser design technology" book by Concept ETI, its very detailed book on diffuser design.
