Hello fellow humans

I am simulating spray combustion, and need to create a new material database for my needs.

My fuel is in the spray, and my oxidant in the continuous phase.

The current model is:

Energy on, k-ε, DPM and species transport (eddy dissipation/finite-rate).

My DPM should be a mixture of 3 species, each of which is injected in liquid form, may evaporate in the flame, and combusts.

The question is:
In the species model i am asked for a mixture material.
Does this mixture have to contain all of the species in my computational
domain (such as ambient air)? and if so, do i include the DPM species?

As a follow-up question, for my DPM species which evaporate, when defining the material, how do i specify liquid vs gas phase properties?


Any help is much appreciated
