Laminar flame speeds, counterflow ignition, and kinetic modeling of the butene isomers

Laminar flame speeds and ignition temperatures of nonpremixed counterflow were measured experimentally for the butene isomers at normal and elevated pressures. Results show that the flame speed increases in the order of isobutene, trans-2-butene, and 1-butene. Furthermore, isobutene has the highest ignition temperature, while those of trans-2-butene and cis-2-butene are quite similar to each other and are slightly higher than that of 1-butene....
