Turbulent viscosity ratio transition in the boundary layer
 

Hi, friends.
Why there is no transition of turbulent viscosity from the minimum to the maximum then back to the minimum in the near wall region in my simulation in ANSYS FLUENT? The model is circular tube with a diameter of 10mm, and the inlet velocity is 10m/s, it's sure that the flow is turbulent.


I am puzzled with the problem because the ANSYS Theory Guide pointed out that the maximum turbulent viscosity ratio located in the middle of the boundary layer, also in the website of Leap Australia shows a obvious transition.https://www.computationalfluiddynami...oundary-layer/

Are you using the Transition model?
