yow is on a distinguished road
I've been following a basic tutorial for droplet combustion: https://www.youtube.com/watch?v=sg3jcwZGXM4&t=310s

I think the only major difference is that I've specified .00096 kg/s injection flow rate of diesel fuel (.5 equivalence ratio) in the discrete phase tab. When I run my iterations, the mass flux reports double that: .00192 kg/s. Is this my error or can Fluent only work with stoichiometric ratios for droplet combustion?

Also, I have trouble achieving continuity convergence - always more than 1e-2 and net mass flow continues to change. I'm using a coupled solver with Courant # = 4, .1 pressure and momentum UDFs, PRESTO! for pressure, and second order for all others. I imported cold flow interpolation that had good convergence. Any help with hot flow convergence is appreciated.
