Hi
You can see in attached picture that I have a probleme with water velocity Can anyone help me de resolve this problem ? I used MRF and k-e RNG approach W= 100 rpm material: water solver: SIMPLE Meshing : non conformal patch (see picture) |

Hi,
A few suggestions: try k-e standard, slice your geometry at the bottom part, I believe you can get hex elements for the Rushton blades and try different dimensions for the rotational zones And a couple of questions: What component of the velocity is the first contour? Could you please attach the contour plot of axial velocity in a vertical plane (xy in your geometry) Please include the number of cells and the mesh quality in your reply. Overall, I think the mesh is causing all the troubles. To me it looks kinda coarse, especially where the top rotational zone touches the rest of the tank. Cheers! |
