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 __________ Rasoul |

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 _________ Rasoul |
