Two fuel injection for combustion inside a LPRE using sprayFoam.

kanishque · October 27, 2022, 04:14

Hello,

I'm trying to simulate spray break-up and combustion of two hypergolic propellants using sprayFoam. The main issue I'm facing is, 'how to model the injection of two fuel sprays'. My injection surface needs to be a disc and the spray should come out as a cone. For this I'm confused whether I should coneNozzleInjection or coneInjection. (you may suggest any other injection model, that I might have missed to search upon). And how can I model injection of the two fluids from different surfaces.

It would be a great help, as I'm stuck on this part of modelling for more than a week

I'm actually interested as well if sprayFoam has the capability to model multiple fuels. Did you figure this out?
