radial diffuser

[insideman]

Any one know where I can get detailed information on design of radial diffusers, vaned and vaneless?

Is this for a centrifugal compressor?

 

[insideman]

Fredt: No. This is for a tabletop wind tunnel. An axial fan will drive it. The exhaust will exit through the diffuser if I can get the exit velocity to be low enough to not trouble people in the room or ruffle papers.

Look for some Heating, Ventilation and Air Conditioning (HVAC) theory on this.

The American Society of Heatibg Refigeration and Air Conditioning Engineers (ASHRAE) reference tomes would be a good start. See any ME or Eng. library.

Air Conditioning equipment manufacturers literature on diffuser selection could be immediately useful.
