Hello,

Can any on tell me the step to simulate an 2d vawt in a tunnel. The main problem that i am facing is creating a rotating mesh around the blades.

hi,

Try Moving Reference Frame first. You can shift to Sliding Mesh from Moving Reference Frame once you get a converged solution with Moving Reference Frame.

Cheers

hi..

I am also doing vawt simulation by CFX,
For turbulence model, I am trying to use SST-transition,
I meshed the rotor domain by using CFX mesh and setting y+ equal to 1,
what do you guys think about the mesh, is it too coarse??

doesn't seem too coarse. Maybe transition from boundary layer to "open field" is a bit quick.... but if you results are ok so there's no problem

Hi all, i hope that you are well
i wanna simulate 3D VAWT. i did 2d of this subject with GGI interface between rotational and nonrotational parts with icoDymFOAM solver.it is done successfully.
now, i wanna simulate 3d VAWT, but my experience a bout 3d simulation in OpenFOAM is very low.have you any documention that help me how do it or would you tell me how perform it?

Have Fun

i solved it, tortia. just needed to create 3d interface that cover the rotational part of your problem
now, my question is how to create rotation for each blade, on the other hand, i wanna every blade rotates around its axis as rotate centered around
can every one guide me how do it
tnx
