I have a problem on droplet-droplet combustion. My fuel is in liquid phase and oxidizer is in liquid phase. I want to model reactive multiphase flow. Will it be possible through DPM model in ANSYS Fluent. If yes, please help me in setting the case? Provide me some tutorials in droplet-droplet combustion

This is the schematic representation of flow.

I assume the two liquids evaporate before combusting? Assuming this is the case have a look for the droplet combustion tutorials: you just need two injections to add both components.

@rwoolhou yaa i am assuming both will evaporate before combusting. The problem is i am not able to put both fuel and oxidiser as droplet particle. If oxidiser is assumed droplet partcle in DPM, the fuel am not able to assume droplet particle , only inert particle is switching on

You need two droplet materials and two (or more injections). Both can be set as injections and you just then need to set the evaporating species to whatever it should be.

But once I select one as droplet, other am not able to select as droplet. Only inert particle is available

Weird: can you post screen shots of the injection panels?
