If you have several injectors that inject different parcels, how to model their evaporation in CONVERGE?
In your example, you use DIESEL2 as a parcel and C7H16 as its evaporation source that included in therm and mech files.
I think that we can use a composite file as evaporation sources, however, the code takes the mass diffusivity constants for a fuel.
Should we use a UDF file or a reasonable assumption?
My next question is : How to choose fuel_name for a blend of fuels in the SAGE solver?

Hi,


You can tune the mass diffusivity in spray.in like this:

5.44e-06 evap_d0_diffuse Liquid species mass diffusivity variable (gas state).
1.6 evap_n_diffuse Liquid species mass diffusivity variable (gas state).

Currently, we assume they are constant for each liquids. User can change them in user_spray_evap.c.

For your second question, this name is not used in the SAGE solver, so basically you can specify whatever name you want and will not make a difference.
