I am conducting a study into turbulent flow around imperfect cylinders. I am relatively new to turbulence modelling.
I have a cylinder placed in a rectangular domain and I am simulating and external flow at Re 20000 using the Spalart Almaras model. Cylinder diamter is 0.01m.
Does anyone have any suggestions for how to calculate or what values to use for Turbulence Intensity, Turbulence Length Scale and Turbulence Velocity Scale?

Thanks
