Ignition Delay-Times of n-Pentane in a Shock Tube

  • Alexander Burcat

Abstract

The combustion kinetics of n-pentane was investigated in detail for the first time. Ignition delay times of n-C5H12 and Oxygen mixtures diluted in Argon were measured over a wide range of compositions, pressures and temperatures. The 240 experiments were statistically correlated to an overall equation
$$\tau = {10^{ - 12.8}}\exp [ + 34610/RT] \times {[{C_5}{H_{12}}]^{0.29}}{[{O^2}]^{ - 1.10}}{[Ar]^{0.13}}\sec.$$
An effort was made to check and reduce the 325 reaction kinetic scheme.
