Source term from droplet evaporation

erikrijk · August 20, 2009, 09:39

Hi all,

I'm simulating fuel injection using the Lagrangian multiphase option. Droplets are evaporating to scalar(01). Now I want to determine a mixture fraction, using sorsca.f. Therefore I need the source term that represents the addition of fuel into the gaseous phase originating from the fuel droplets. Does anybody know how to extract this value from Star?

Thanks!

Erik

I'm not sure what you are trying to accomplish. The code all ready handles what you describe.

Computing mass fractions & sources terms are typically done within posdat & then passed to the source scalar subroutine.
