Stiff chemistry solver validation test cases
gri : GRI-Mech 3.0. CH4 combustion, 53 species, 325 reactions
h2 : H2 combustion, 10 species, 27 reactions
nc7h16 : n-Heptane combustion, 544 species, 2446 reactions
ic8h18 : iso-Octane combustion, 874 species, 3796 reactions
Results interpreted in 'validation' sub-folder, where OpenFOAM results
are compared against those predicted by
Senkin (
CHEMKIN II
)
are compared against those predicted by CHEMKIN II
.
Overall the best performing ODE solver is seulex followed closely by rodas32.
