 February 3, 2015, 01:59 sprayFoam: more than one inert specie? #1 Member   Neilson Whit Join Date: Aug 2011 Location: Japan Posts: 57 Rep Power: 7 Dear All in sprayFoam, is is possible to use two inert species? In the tutorial, only one inert specie is written in the constant/thermophysicalProperties file... thanks

Hi
I think it's not possible to set two inert species. if you look YEqn.H ,solver calculates mass fraction of inert of231)
Code:
`Y[inertIndex] = scalar(1) - Yt;`
that Yt=mass fractions of all species except inert specie
so if you use two inert species for example A & B, solver is not able to calculate mass fraction of them.

in /opt/openfoam231/src/lagrangian/intermediate/phaseProperties/phaseProperties
Code:
```//- List of component mass fractions
scalarField Y_;```

Atmosphere is steam and air mixture. I am confused with what should be the inert specie? which specie is carrier specie?
