Hi everyone,

I want to simulate the combustion in the cylinder with the G-equation, how to combined the G-equation with PSR(Perfect Stirred Reactor) on the unburned zone.

Thanks !

Note that in CONVERGE mixture composition in each cell is assumed homogeneous (perfectly stirred)

The G-Equation offers the following three options,
(1) Equilibrium inside flame - Here CONVERGE uses CEQ at the flame front and inside
the flame (burnt gases).
(2) Equilibrium inside flame (burnt gas) and SAGE outside flame (unburnt gas) - Here CEQ at the flame front and inside the flame (burnt gases) while SAGE outside the flame (unburnt gases)
(3) SAGE inside and outside flame - Here CEQ is used at the flame front while SAGE is used inside and outside the flame (burnt and unburnt gases)

CEQ -> Licensed from Ithaca Combustion Enterprise is a solver to calculate the equilibrium
SAGE -> Detailed chemistry solver
