Hi all,

i need to model on CCM+ the velocity distribution of an helicopter rotor, without modelling the rotor-blades.
For this pourpose, i think it's a good choice model a disc set as inlet surface and define a field function representing the average velocity distribution in a cylincrical coordinate system.

Anyone can suggest other solutions?

Thanks,

Alessandro

Do you think this will be able to capture the 3-D effects of the rotor blade rotation? If you are not keen on these then I guess this should work.

Hi,

i know this model doesn't capture the 3D effects, i'm not analizing the rotor blade, just the effects of the landing on the helideck of a motoryacht and on the exhaust gas outgoing from chimney.
Any suggestion is accepted.

Bye
