Effect of Electric Field on Growth Kinetics, Morphology and Wettability of Flame‐Deposited Carbon Nanoparticle Coatings

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.
A novel electric field‐assisted thermophoretic flame synthesis process enables rapid deposition of carbon nanoparticle films with tunable wettability. Applying a negative voltage during flame exposure accelerates growth, increases surface roughness, and alters morphology.

The Influence of Hydrocarbon Additives on Laminar Burning Velocity and NOx Emissions in Hydrogen‐Air Combustion

open access: yesPAMM, Volume 25, Issue 4, December 2025.
ABSTRACT Hydrogen is a promising carbon‐free fuel but faces challenges due to combustion instability and nitrogen oxide (NOx${\rm NO}_x$) emissions during combustion. This study investigates the potential of blending hydrocarbons (methane, propane) or ammonia with hydrogen‐air flames in order to minimize these challenges.

Effects of Mean Inflow Velocity and Droplet Diameter on the Propagation of Turbulent V-Shaped Flames in Droplet-Laden Mixtures

open access: yesFluids, 2020
Three-dimensional carrier phase Direct Numerical Simulations of V-shaped n-heptane spray flames have been performed for different initially mono-sized droplet diameters to investigate the influence of mean flow velocity on the burning rate and flame ...

Thermal Release Characteristics of Aeroengine Combustor Outlet Modulated by Gliding Arc Plasma

open access: yesAdvanced Science, Volume 12, Issue 41, November 6, 2025.
Gliding arc plasma‐assisted combustion significantly improves aeroengine combustor. Gliding arc plasma moves flames closer to the fuel source, enabling complete burning. This increases the combustion efficiency by 10.3% and raises outlet temperature by 141.6°C.

Inhibition Characteristics of Methane/Air Explosions by Collaborative Inhibition Devices

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 20, Issue 6, November/December 2025.
ABSTRACT With the advancement of the modernization and intensification of urban pipelines, the utility tunnels have become important public infrastructure in the new urban areas of our country. In case of a gas explosion accident, it will seriously endanger public safety. To reveal the mechanism of the collaborative effect of water mist and porous slip

Matrix-free continuation of limit cycles and their bifurcations for a ducted premixed flame

open access: yesJournal of Fluid Mechanics, 2014
Many experimental studies have demonstrated that ducted premixed flames exhibit stable limit cycles in some regions of parameter space. Recent experiments have also shown that these (period-1) limit cycles subsequently bifurcate to period- $2^{n ...

Optimizing jojoba oil methanolysis of cis‐13‐docosenol fatty alcohol to unveil its immunomodulatory potential: a circular biorefinery perspective

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 2146-2160, November/December 2025.
Abstract The sustainable production of jojoba oil derivatives depends on research and development focused on eco‐friendly valorization processes. This study establishes optimal conditions for converting jojoba oil into jojobyl alcohols, which is a key step in realizing its economic potential.

A high-pressure premixed flat-flame burner for chemical process studies [PDF]

open access: yes
A premixed flat-flame burner was designed and tested with methane-air mixtures at pressures from 1.1 to 20 atm and equivalence ratios from 0.7 to 1.1. Reactant velocity in the burner mixing chamber was used to characterize the range of stable flames at ...
