Rotating detonation combustion of liquid kerosene under near-ramjet limit conditions
AIP Advances, 2023 The feasibility of using preheated kerosene and pre-evaporation to assist in liquid kerosene detonation ignition and self-sustaining combustion under near-ramjet limit conditions was investigated. Additionally, the detonation decoupling and self-sustaining mechanisms were analyzed in depth. Owing to the forced heat transfer effect of supersonic flow on

Experimental investigations of mixing characteristics in model rotating detonation engine geometries [PDF]
, 2017 This work examines the mechanisms of reactant mixing in a model Rotating Detonation Engine (RDE) geometry. RDEs are emerging as one of the highest potential applications for achieving Pressure Gain Combustion (PGC). Reactant mixing has been identified as

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Deep Underground Science and Engineering, EarlyView.The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

Engineering Reports, Volume 8, Issue 2, February 2026.This study evaluates the performance and emissions of CI engines using biodiesel blends derived from rice bran and waste cooking oil, revealing that a 30% biodiesel blend significantly reduces emissions, while a 70% blend affects specific engine parameters. ABSTRACT This research investigates the performance, combustion, and emission characteristics of
