Premixed flame ignition is a fundamental issue in combustion. A basic understanding of this
phenomenon is crucial for fire safety control and for the development of advanced …

Abstract Machine learning has long been considered a black box for predicting combustion
chemical kinetics due to the extremely large number of parameters and the lack of …

Cool flame speed is a fundamental parameter, which requires special consideration in
terrestrial measurement due to the slow propagation of the cool flame, the intrusion of …

Hydrogen is widely perceived as the next generation of clean energy due to its zero carbon
emissions. However, there is an escalating concern regarding hydrogen safety. A deeper …

Fuel chemistry represents a typical complex system involving thousands of intermediate
species and elementary reactions. Traditional mechanism reduction methods, such as …

Abstract Simultaneous, dual-perspective, high-speed imaging is used to provide new insight
into the morphology of flames generated at high unburned-gas temperatures behind …

Developed through the combination of two preexisting methods—a shock tube acting as an
impulse heater and a flame speed measurement from a spherically expanding flame—the …

Experimentally measured values of the laminar flame speed (SL) are reported for the
primary reference fuels over a range of unburned-gas temperatures (Tu) spanning from …

Spherical cool, warm, and hot flames and their transitions during shock-flame interactions
(SFI) are numerically studied using dimethyl ether (DME)/air mixtures. The flame dynamic …

Hotspot ignition is a key problem in fundamental flame initiation, combustion control and
prevention of abnormal combustion phenomena. Depending on the characteristics of the …
