[Timur]

Dear all,

I am simulating a slurry flow in a pipe (3D case) with a diameter of 3,2 cm, velocity of 1 m/s. Based on the estimation of the first layer thickness at y+=1, I have to have something about 1,6e-5 m. When I do meshing with sweep method and inflation layers, I get very high skewness as well as high aspect ratio in the boundary layer region which is obvious. I am not sure what can I do with this problem. My questions are:

1) Can I simulate the flow even with high skewness but with "correct' first layer thickness?

2) Can I use Enhaced wall treatment in this cases and do not make the boundary layers so thin?

3) Will the EWT work properly if my boundary layers are not very fined?

Thank you very much in advanced for your replies.
