HELP! post processing for spray modelling
 

Hello all,

I am a masters student using cfd to model injector spray within a car intake system. The spray is defined as a cone

The model iterates over a time period with a fluctuating pressure outlet boundary condition in "sucking" form.

The model seems to run without issues however where i have defined simulation activities to record particle tracks showing droplet diameters. I have also requested mass fractions of the spray material at the outlet.

The problem I have is where I go to post process, results requested of the spray media are not present where pressures and velocities etc are.

Does anyone have any suggestions on something I may have missed?

Many thanks

Hey Hamish

I am looking at the particle diameter change during my simulation. your note rang a bell that you may have done the same thing. Just wanted to ask you how can I monitor the changes of particle diameter during my simulation?
