Bottom wall relevant variables
 

Hi All,

I am simulating flow through a pipe with a cylindrical obstruction in the middle. At the outlet, in addition to the x-viscous shear stress on the bottom wall, we are to produce graphs on two other relevant variables that provide the reader with quantitative detail on the boundary layer of said bottom wall.
This is my first tangle with CFD, and I'm a little stumped on which variables to add.

Please let me know your thoughts.

Any help is much appreciated.

I'm thinking y pressure component and change in u-velcoity with y (du/dy).

Y pressure component in conjuction with x-shear stress to assess if the pipe is taking beating.

The change in u velocity to assess turbulence and entrance length for downstream equipment sake.

So again, any help would be appreciated.
