Hello All,

I would like to know which parameter could be adjusted if the CFD results are smaller than the experiment values, about 18%.

Usually, I change the mesh around the bounday, like the thickness and growth rate. Although the mesh is impeccable, the the vlaues are still unsatisfactory. By the way, I am using the LES.

So anyone could give me some advice on this issue? Thank you for any reply.

Regards

How do you know the mesh is impeccable? Have you done a mesh sensitivity study?
