DNS of a Fully Developed Turbulent Pipe Flow

abdulra5 · August 28, 2018, 19:48

Dear all,

I have performed a DNS on a fully developed turbulent pipe flow, and I have applied periodic boundary conditions on the streamwise direction. At checking, the axial velocities are identical at the ends of the pipe, but the other components are not. I am just wondering if the periodicity is applied correctly or not.

Any help would be greatly appreciated.

Can you share your boundary file and 0 folder?

Actually, I am doing DNS by using Nek5000, not OpenFoam. Sorry.
