wind engineering problem
 

Hi,I am a beginner studying wind engineering and have some confusing problems.

1. About Re, How do we deal with Re between scale ABL wind tunnel and wind environment? In scale wind tunnel, the re is smaller than the real wind environment. so it leads to the turbulence viscosity ratio is larger than 10-5 in the real world. Can I just change the limitation to 10-7?

2. Turbulence Model Which turbulence model is suitable to study wind environment?

Thanks in advance
