I need to examine the concentration of n2o in a room. The source of n2o is a person breathing with the mixture gas contains of n2o(40 ppm) and air. The airflow from the mouth is 7 l/min. I need to obtain results of n2o distribution in the room. I have a lot of problems with setting it up as well as preparing results in post, which I'd like it to be in ppm units. I will be gratefull for any advise.

hi,

This should be easily modelled with a passive scalar. In CFX-Post you should be able to convert from the solver units (probably kg of n2o per kg of air) to ppm for visualisation.

The problem is that I've only managed to give quantity of N2O in [kg/s]- I've made it in CFX Pre.(I'm not sure if I set it up correctly ). More details, please - I'm not advanced user.
