Shock Tube Ignition and CH4 Time-Histories during Propanal Oxidation

Propanal is an aldehyde intermediate formed during hydrocarbon combustion process. In this paper, we provide ignition delay time measurements behind reflected shock waves for stochiometric (Φ = 1) mixtures of propanal (CH3CH2CHO) and oxygen (O2) in argon bath gas at temperatures of 1100 < T < 1500 K and pressures around 1 atm. The measurements were conducted using the kinetics shock tube facility at UCF. The results were compared to data available in the literature as well as the predictions of three different aldehyde kinetic models. In addition, we used the laser absorption diagnostics for measuring methane (CH4) time-histories behind the reflected shock waves using a continuous wave distributed feedback interband cascade laser centered at 3403.4 nm. Methane concentration time histories were obtained for pyrolysis of propanal at 1300 K and around atmospheric pressures.
