Abstract: 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 … Show more

“…Autoignition determines the knock limits of spark ignition engines [1] and the efficiency and emissions of compression ignition engines [2]. Aero-engines and stationary power generation turbines control autoignition for safety reasons and/or to extend operability limits [3]. This work aims to provide new insights into the ignition characteristics of n-heptane, a widely used surrogate molecule for studying combustion of practical hydrocarbon fuels [4,5].…”

“…RCMs are typically used for laboratory studies of fuels and combustion kinetics, as well as sensor validation in realistic, engine-like conditions [2]. RCMs generally utilize one or more pneumatically driven pistons that, when released, rapidly compress a gas sample with a compression ratio of 10 to 20, resulting in elevated compressed pressures and temperatures (e.g.…”

“…RCMs generally utilize one or more pneumatically driven pistons that, when released, rapidly compress a gas sample with a compression ratio of 10 to 20, resulting in elevated compressed pressures and temperatures (e.g. 10 to 30 bar, 500 to 1000 K) The compression process can occur in as little as 2 ms, and thus is often considered analogous to a single compression stroke of an internal combustion engine [2]. The combination of short timescales with rapidly varying thermodynamic conditions provides a realistic and demanding system in which sensors can be tested and validated.…”

“…In order to accurately include the change in pressure/temperature before and after compression, the non-reactive profile is converted into a normalized effective volume profile through the isentropic relationship between pressure and density, thereby allowing the calculation of the effective volume. This method of RCM simulation has been used previously in many studies [51][52][53][54][55] to simulate the various RCM facilities.…”
