How to obtain the mass fraction of evaporated diesel spray
 
Hello everybody! I'm a newcomer to CFD Online and I'm using Fluent to simulate the diesel spray inside the cylinder.

I'm using the Discrete Phase Model, for the injector, I chose the plain-orifice-atomizer. I've saved the case and data files after the start of injection per degree crankshaft angle. What I'm having problems with are:

1. How to know the mass fraction of diesel spray that's evaporated, and meanwhile, the mass fraction that's still in liquid phase.

2. How to obtain the mass fraction distribution of the fuel. For example, for the part of fuel with 10% mass fraction in the cylinder, it represents 7% of total mass of the diesel injected.

Thanks!
