Hi !
I am running a simulation of ammonia combustion in a ICE. I wanted to plot average pressure, temperature, and species concentration during the cycle. I used for that the option "volume-averaged" in solve==> monitors ===> volume... But i don't really know the difference between this and "mass-averaged" . I know it already has been discussed, and it seems that for compressible fluids, "volume averaged" is ok for pressure... but what for the species concentration ? I mean, i want to compare for example exhaust NO mole fraction with existing results, should i use "mass-averaged" ? Thanks a lot ! |
