Read the model definitions in the User's Guide, in your case I suspect DPM is the best option, but will leave you to check and explain why. nFor the rest of the set up, you'll need a mixture in the gas phase (air and whatever is evaporating) and for the droplets it'll depend on which model you use. If you do use DPM read up on the combusting multicomponent particles: we're not burning anything but do need to account for the droplet liquid & (I assume) solid part. nThe evaporation will follow from the method you choose.RE the pressure bc's. Do you know the flow or are you replicating the normal 4kPa suction used for an inhaler? There are several papers on this so it's public domain: you'll note from reading the rules how much we can explain. n
