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.

I have another question...

In the sprayFoam, the input parameters for the gas species are mole fractions? or mass fractions?

thanks

I see...

i am trying to simulate water vapour condensation on the subcooled spray droplets.
Atmosphere is steam and air mixture. I am confused with what should be the inert specie?
which specie is carrier specie?
