How can I set turbulence and viscosity configuration????

sunti · November 24, 2011, 04:28

Hello
I need to run a simulation of an antenna mounted to the belly of an aircraft. The aircraft is cruising at 140m/s at 2000ft. Which turbulence model would be suitable for this case?
I would also like to know how to estimate the turbulence intensity and freestream viscosity ratio.

Thankful for any suggestions!

Thank you so much.
This help me got the turbulence intensity and viscosity ratio and maybe my simulation can run without any problem.
