Modelling a propeller with actuator disc
 
Hello everybody.

I am currently working on the CFD analysis of a Mini UAV (Unammned Aerial Vehicle) with Fluent, and I would like to model the propeller at the back of the UAV with an actuator disc. My supervisor told me it could be possible on Fluent but I really don't know how to do it. Should I create a disc without any thickness..?What kind of boundary should I put (fan...???). Should you have any idea about it, I would appreciate a lot your help. Thank you all in advance.

Re: Modelling a propeller with actuator disc
 
Hi, Depending on the simulation conditions, you may consider the following: 1. Rotational periodic flow 2. Multiframe rotating reference frames 3. For inlet you can use either velocity inlet boundary condition, if you the know the flowrate; or pressure inlet boundary condition if you know the pressure difference across the propeller.
