How to simulate the flow around a helicopter rotor
 
Hello,

it is posibile to model in Fluent the flow around a helicopter rotor ?

Thanks.

Why not?

If you have the dimensions, I can't see what the problem is. Maybe you would need to use MDM or Sliding mesh.

Kind Regards

yeah sure u can , but it needs a lot of work and it is really fun . I think and agree on what AAA said , u can use the sliding mesh or Multiple rotating reference frame or Dynamic meshes . the 3 are applicable , I would prefer Dynamics mesh , it needs work , or MRF .

Best option is to use the Virtual Blade Model (VBM). It been designed for helo rotors. It sources in momentum and swirl to a circular interior zone so not necessary to run sliding/transient.
