Can anybody explain to me the Coandă effect well? I am finding that many definitions and explanations conflict.
I am particularly confused about the following points regarding the Coandă effect:
- whether the Coandă effect is the same as normal boundary layer attachment to a surface
- whether the Coandă effect is only defined for convex surfaces over which a jet (of the same state as the surrounding fluid) is tangentially blown
- what causes the Coandă effect: the jet entraining the ambient fluid or a balance of pressure and centrifugal forces, or something else?
