...Zhaoming Mai; Yingtao Wu; Chenglong Tang; Wei Wang; Zuohua Huang To understand the effect of n -heptane (NC 7 H 16 ) addition on the auto-ignition of methane (CH 4 ) at low to intermediate temperatures, the ignition delay times (IDTs) of stoichiometric CH 4 /NC 7 H 16 blends with varying NC 7 H 16...

...Michael Pierro; Justin J. Urso; Ramees K. Rahman; Christopher W. Dennis; Marley A. Albright; Jonathan McGaunn; Cory Kinney; Subith S. Vasu Ignition delay times from undiluted mixtures of natural gas (NG)/H 2 /Air and NG/NH 3 /Air were measured using a high-pressure shock tube at the University...

... combustion, two different definitions of ignition delay time (IDT) were considered: sidewall OH* chemiluminescence and sidewall pressure. Both definitions were used to create temperature-dependent correlations for each of the lubricating oils. In general, both definitions provided similar results within...

... /CO/CO 2 mixtures is required. Time-resolved speciation measurements for target species have been shown to better aid in improving the understanding of underlying chemical kinetics than global ignition delay time measurements. Therefore, laser absorption measurements of CO were measured behind...

... a wide range of ambient temperature and pressure conditions in an optical rapid compression machine. Specifically, the spray development and ignition process are first visualized and the spray ignition delay times (IDT I ) are measured through high-speed imaging. IDT I is then compared with gas phase...

... of 3 and 6 bar. Furthermore, the impact of TMOF addition to a gasoline surrogate (PRF90) on ignition delay times was studied using the shock tube method at φ = 1.0, 1:5 dilution with N 2 , T = 900–2000 K, and at 4 bar. The experimental data sets have been compared with predictions of the in-house...

... understanding of their combustion properties is required for their safe and efficient utilization. In this study, the results of a combined experimental and modeling work on oxidation of OME 2 are reported: (i) Ignition delay time measurements of stoichiometric OME 2 /synthetic air mixtures diluted 1:5...
