I’m unsure what you mean by volume fraction. Do you mean how much of the cell is DPM? I think my case is a bit weird because my continuous phase is just made up of 100% evaporated particles.

I was able to lower the tracking from 50,000 to 1,500 and decrease the time step size to 3e-4, which seems to stop particles from building up, but now k and epsilon residuals keep spiking and falling back down again after all other residuals have leveled off. Should I try a different turbulence model?

In terms of LWF, should I turn that on in addition to the rest of my model? It’s unclear what you mean by LWF should be sufficient, as the placement of the injectors matches up with a physical machined injector, and it seems adding LWF will just complicate the model further. Also I’m not sure if LWF makes sense because at those temps won’t the injected fuel vaporize into a gas?
