setting Boundary condition for additional variable
HE ALL ;
I want to set Boundary condition for pollutant ( CO) as aditional variable my line source is in the ground a street at level z=0 .
my Boundary parts are
INLET, OUTLET, symetry ( SIDES 1 et 2) , GROUND , TOP , SOURCE
the emission rate from the source is 0.0001 Kg/s.
If any one experienced can help
Sounds straight forward. Have you done the tutorials? That will give you some tips on how to get started.
Or what specific problem do you have in setting it up?
firstly, I took a look in tutorial , there is an exemple wich treate smoke dispersion. My case deel with a tracer gaz (SF6) realised from a line source within a street. the emission rate is 0.0001 kg/m^3. To simulate the concentration of SF6 I used an additional varaiable CSF6 with a transport equation .
I choose for CSF6 BC :
INLET Value CSF6 =0
OUTLET ZERO FLUX
SYMETRY ( SIDES) ZERO FLUX
TOP ZERO FLUX
GROUND AND LINE SOURCE CSF6 = 0
the simulate concentration CSF6 = f(Z) seems wrong because the minimum conentration value was located at level z=0 wich is not correct.
