Agreed. It is a common mistake to jump into the model everything approach when you can learn far more with simpler models of sub-systems and achieve it in reasonable time frames. And if you cannot...

But what are you doing this model to tell you?

There are many approaches - from assuming the droplets are inert particles through to a full phase change model - but until I understand what is...

If you are just trying to extract droplets from the flow then just call then droplets an inert particle. But I doubt...
