prashantthaker208 is on a distinguished road
hi users,
i am modeling pollutant transport without reactions.

In the species transport model, I turn on 'inlet diffusion' with CO-air as the mixture template.
I have one inlet (velocity inlet) for the ambient air where i do not specify any mass fraction of species.

the other inlet is a road which i model as mass flow inlet with constant mass flux. Here I specify only CO mass fraction as 1.

In the results, i get very high CO concentration ( about 10^-4 kmol/m3)

Where am I going wrong??
Please help,

Thanks in advance,
