Insights into the underlying reaction kinetics of gasoline–ethanol interactions and their effects on the auto-ignition characteristics of gasoline/ethanol blends

Applications in Energy and Combustion Science
Ethanol-blended gasolines show enhanced anti-knock behavior in spark-ignition engines. Fundamental experimental investigations on their auto-ignition behavior are however scarce in the literature.

Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

Auto-ignition Temperature Test Device for Crude Oil in In-situ Combustion

Shiyou jixie, 2017
In order to solve the problem that the ignition temperature is too high to cause the deformation of the pipe string in the process of in-situ combustion, a test device for auto-ignition temperature of crude oil has been developed.

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

Polymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Experimental Study of Ignition over Impact-Driven Supersonic Liquid Fuel Jet

Advances in Mechanical Engineering, 2013
This study experimentally investigates the mechanism of the ignition of the supersonic liquid fuel jet by the visualization. N-Hexadecane having the cetane number of 100 was used as a liquid for the jet in order to enhance the ignition potential of the ...

Assessment of implementation variants of conditional scalar dissipation rate in LES-CMC simulation of auto-ignition of hydrogen jet

Archives of Mechanics, 2013
In this paper the large eddy simulation (LES) and conditional moment closure (CMC) combustion model have been applied for modelling of auto-ignition of hydrogen jet issuing into a hot ambient co-flow.

Effects of temperature and composition inhomogeneity on the ignition characteristics of NH3/H2 co-firing fuels under HCCI operating conditions

Applications in Energy and Combustion Science, 2023
The application of ammonia (NH3) in combustion devices, such as internal combustion engines (ICEs), is expected to largely reduce the greenhouse gas (CO2) emission.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Dry Development of Dry Coated Sn‐Based Inorganic Resist for Defect‐Suppressed and High‐Resolution Patterning Process

Small Methods, EarlyView.
This work compares conventional wet development and asynchronously pulsed plasma development for Sn‐based inorganic resists under delay and AMC exposure. While wet development induces CD variation, scumming, and bridging, pulsed plasma enables selective removal of non‐exposed regions, mitigating contamination effects and achieving defect‐suppressed ...
