HELP with the simulation of a propeller

      Hi, I am trying to simulate an actuator disk to show results as a drone propeller. Firstly I calculate the pressure drop of the actual drone propeller between upper and lower surface (see image) and now I am trying to set this pressure drop onto the disk actuator simulation by setting a plain surface with the diameter of the propeller as a fan. My main problem is that if I only set the pressure drop as a constant I do not get accurate results, so I would like to know if I should also set the swirl - velocity specification on the fan dialog box and if so, how can I get those parameters from the actual propeller simulation? Since I am a bit lost right now.

      Thanks in advance.

      Hello, 

      are you using 3D Fan zone? 

      Constant pressure is obviously just an approximation. Typically, this pressure drop will be a function of the amount of air passing through the propeller. Do you have only this 1 data point from the actual drone propeller?

      Hi, I am using just the fan condition for a surface. This is the relevant data I got from the propeller simulations
