Problem with stirred mixing tank
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
Meshing : non conformal patch (see picture)
Problem are solved :)
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.
