Regarding discrete phase
 

Hi, good day.
In Fluent, under discrete phase model, injection can be created.
In injection, we get to choose the evaporating species, what is meant by evaporating species? i read through the user manual, but it does not clear my doubt.
Help is really appreciated. Thanks a lot. =)

I am actually simulating diesel combustion. I used non premixed combustion model and discrete phase model. I created an injection to inject diesel into the pdf mixture. the evaporating species is confusing me as, the fuel injected into the mixture is diesel, but why i can choose species that made up of pdf mixture under evaporating species?
