Dear All,

I am simulating the dispersion of CO2 gas in the atmosphere. I used UDFs to define the wind profile at inlet. The turbulence model was chosen to model. Firstly I run the steady to get the full development of wind in the domain without CO2 . Then I run the transient for the dispersion of CO2 and air. I used SIMPLE for both steady and transient. However the simulation result is not same with the experimental data. Please look at the picture. Does anybody know how to set up the transient to get the same of the experimental data? Thank you
