You can use VOF to DPM to capture the break up but evaporating and burning the VOF part isn't simple and the mesh requirements likely make it too computationally expensive given you're then looking at the rest of the domain. 

The nozzle/atomiser injection types may be suitable, otherwise you may find the nozzle data will give sufficient information. Alternatively you can model the nozzle in one case to find the droplet distribution and then map that into a second case to use DPM for the combustion part.Â
