How do I monitor the turbulence of the flow?

Hi,

I am new in CFD. Can I know how do I monitor the turbulence of the flow at a specific surface, in my case the inlet and outlet. Thanks.

You can guess it, or you can pretend that you understand turbulence (when nobody else does) and make a calculation based on some form of voodoo.

Write the output of velocity at few points on the surface with time. If you are performing unsteady calculations, you should observe fluctuations in the fields. Also you can write out snapshots of the flowfield on the surface at different times and visualize it. You should be able to see the instantaneous flow structures.
