Rapid compression machines (RCMs) are widely-used to acquire experimental insights into fuel autoignition and pollutant formation chemistry, especially at conditions relevant to current and future combustion technologies. RCM studies emphasize important experimental regimes, characterized by lowto intermediate-temperatures (600-1200 K) and moderate to high pressures (5-80 bar). At these conditions, which are directly relevant to modern combustion schemes including low temperature combustion (LTC) for internal combustion engines and dry low emissions (DLE) for gas turbine engines, combustion chemistry exhibits complex and experimentally challenging behaviors such as the chemistry attributed to cool flame behavior and the negative temperature coefficient regime. Challenges for studying this regime include that experimental observations can be more sensitive to coupled physicalchemical processes leading to phenomena such as mixed deflagrative/autoignitive combustion. Experimental strategies which leverage the strengths of RCMs have been developed in recent years to make RCMs particularly well suited for elucidating LTC and DLE chemistry, as well as convolved physicalchemical processes. Specifically, this work presents a review of experimental and computational efforts applying RCMs to study autoignition phenomena, and the insights gained through these efforts. A brief history of RCM development is presented towards the steady improvement in design, characterization, instrumentation and data analysis. Novel experimental approaches and measurement techniques, coordinated with computational methods are described which have expanded the utility of RCMs beyond empirical studies of explosion limits to increasingly detailed understanding of autoignition chemistry and the role of physical-chemical interactions. Fundamental insight into the autoignition chemistry of specific fuels is described, demonstrating the extent of knowledge of low-temperature chemistry derived from RCM studies, from simple hydrocarbons to multi-component blends and full-boiling range fuels. Emerging needs and further opportunities are suggested, including investigations of under-explored fuels and the implementation of increasingly higher fidelity diagnostics.

“…Rapid compression machines (RCM) are routinely used to study autoignition of fuels under 65 temperature and pressure of relevance to practical engines. A wide variety of fuels, ranging from 66 pure hydrocarbons to regular gasoline and diesel [1][2][3] can be investigated in an RCM. Figure 1 67 describes a typical RCM experiment where a fuel/oxidizer mixture is rapidly compressed to top dead 68 center (TDC) thereby reaching a higher pressure and temperature.…”

Fuels ranging from pure species to full boiling range gasoline 42 and diesel can be studied in an RCM to develop a better understanding of autoignition kinetics in 43 low to intermediate temperature ranges. In an RCM, autoignition is achieved by compressing a 44 fuel/oxidizer mixture to higher pressure and temperature, thereby initiating chemical reactions 45 promoting ignition. During these experiments, the pressure is continuously monitored and is used to 46 deduce significant events such as the end of compression and the onset of ignition.

“…Gas chromatography was used in their work to measure stable products in tetralin oxidation. Wang et al 18 measured the ignition delay times for tetralin/air mixtures in a shock tube at equivalence ratios of 0.5 and 1.0, pressures of 13 and 37-39 bar, and temperatures from 978 to 1 277 K. Kukkadapu et al 19 investigated the ignition characteristics of tetralin at pressures of 15-50 bar, temperatures of 762-950 K, and equivalence ratios of 0.5 and 1.0 using a rapid compression machine. Recently, Raza et al 20 measured the ignition delay times of tetralin/air mixtures in a heated shock tube at moderate to high temperatures ranging from 830 to 1 380 K, at pressures of 6, 10, 20 bar, and under fuel-lean, stoichiometric, and fuel-rich conditions.…”

This work reports an investigation on laminar premixed flames of tetralin at 30 Torr and equivalence ratios of 0.7 and 1.7. Measurements of the chemical structure including identification and mole fraction measurements of free radicals, isomers, and polycyclic aromatic hydrocarbons (PAHs) were performed using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS). A kinetic model with 296 species and 1 577 reactions was developed and validated against the flame chemical structure data measured in this work. Modeling analysis reveals the key reaction pathways in tetralin decomposition and PAHs formation. The H-atom abstraction reactions by H, O, and OH are found to control the consumption of tetralin in the lean flame, while those by H play the dominant role in the rich flame. Indene and naphthalene have very high concentration levels in the rich tetralin flame due to the existence of direct formation pathways from the decomposition of tetralin. The two bicyclic PAHs and their radicals play significant roles in the PAHs growth process of tetralin combustion, which results in the high sooting tendency of tetralin compared to those of alkylbenzenes with smaller or same carbon atom numbers.
