Thermal phase change model is not proper for multicomponent flow. You need to drive your bulk phase change by means of relative humdity say partial pressure to saturation pressure. You can even use the Lee model but adjust the saturation temperature to fulfill Antoine equation at RH Equal t0 100%. On the other hand you can make use of the Ddpm Model and get advantage of the more accurate heat and mass transfer for DPM for combustion or droplet or multicomponent particle.
