Equilibrium I
- Notes: equilibrium reactions, Keq
- Notes: equilibrium criteria
- Compare EQ, PCC, WGS , [notebook (needs streams.py) ]
- streams.py (right click, save as)
- This is a nice helper class for doing many of the calculations demonstrated previously.
- Uses Cantera
- Define the composition of the $\xi=0$ and $\xi=1$ streams.
- Functions provided for:
- compute $\xi_{st}$
- pure mixing state: h and y from, e.g. $h=h_0(1-\xi) + h_1\xi$
- products of complete combustion (x or y) and temperature for given $\xi$
- equilibrium products (x or y) and temperature for given $\xi$
- products of complete combustion with water gas shift equilibrium, and temperature for given $\xi$
- $\Phi$ from $\xi$ and $\xi$ from $\Phi$
- y from x and x from y
Equilibrium II: minimize Gibbs: element potential method
- Notes and solver , [notebook (needs streams.py) ]
- streams.py (right click, save as)
- simple mechanism file from gri30.yaml, but without reactions. Can edit species list.
