Show D. Marlow and T. S. Norton times (10~ to 10.1 s, T = 1700 K) and temperatures (1300 to 2000 K, 't = 10.2 s). The largest discrepancies were observed for fuel-rich combustion at low temperatures. For these conditions, the skeletal mechanism disagrees with the detailed mechanism, suggesting that C2 reactions important for these conditions have been neglected in the skeletal mechanism. Future work will test the performance of the reduced and skeletal mechanisms in models of laminar, counterflow flames. If the mechanisms succeed in modeling the chemistry in both the PSR and these flames, then we expect them to succeed in modeling turbulent flames, which are composed primarily of distributed reaction zones (similar to combustion in the PSR) and flamelets (similar to counterflow flames).
