Hi,

I'm looking for the best model for gas dispersion modelisation.
the released quantities are small ( 0.5 to 30 g/s) so the concentration are significant in neighborhood of 20-30 m maximum.
The most of the time 0.5 - 4 m.
I'ma looking for a model that take in account buoyancy and obstacle in account.
There is gaussian model and integral model.
Wich is the best ?
I know that i'm in a forum cfd but a comparaison is interessing of if thez are cfd models that are accessibles, i'm interessted,

thanks
