How to track spray liquid\gas phases (for DPM source)?

Jasmine :) · March 21, 2015, 09:33

Hi,
I'm new to Fluent and will appreciate your advice and help.
The problem that I work on considers a non-premixed spray fuel combustion with air, using DPM for fuel injection.

I'd like to trace the fuel liquid mass fracture in the spray stream (liquid+gas) as it evaporates (until it is fully evaporated and burned)

Thanks!

You can check mass fractions via Contours-->Species-->Mass Fraction of *.*. Also you can trace the DPM particles with Particle Tracks.

Thanks,
Within a specific material, how can I distiguish a liquid phase mass fraction from gas\evaporated phase?

Does a mass fraction (contours\xy\..) of that material represent liquid phase only, or all phases?

You can chose the species for which you want to see the mass fraction. Depending on your setup you should be able to see all the species participating in the simulation.
