Hi everybody

I simulate gas dispersion in atmosphere, how can I know turbulence intensity and length scale in air inlet or gas inlet?

Thanks

Hi,

This should be reported in the experimental results you are trying to reproduce.

Hi It's a field experiment and I have only wind data (speed, direction) with time and height. I havent any turbulency data!

Hi,

Look in the literature and find what a typical atmospheric turbulence profile would be then. Also, depending on the simulation it might not be that sensitive to the exact turbulence level so a guess is OK. This is problem dependant and needs to be checked.
