Numerical investigation of forced ignition in laminar counterflow non-premixed methane-air flames [PDF]

, 2007
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an ...

α‐Glucosidase and Acetylcholinesterase (AChE) Inhibitory Activities, Larvicidal Potential and GC–MS Analysis of Endlicheria paniculata: A Combined Experimental and Molecular Docking Study

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
This study investigates the essential oil composition of E. paniculata wood, bark, and leaves by GC–MS. Biological evaluations of the leaf essential oil reveal promising larvicidal potential against Aedes aegypti and in vitro inhibitory activities against α‐glucosidase and acetylcholinesterase (AChE), supported by molecular docking simulations ...

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, Volume 14, Issue 10, Page 4546-4583, October 2026.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

Applications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Effect of Different Acoustic Parameters on NOx Emissions of Partially Premixed Flame

Applied Sciences, 2019
The effects of acoustic frequency (f)/0–400 Hz and amplitude (A)/0–1400 Pa on nitrogen oxides (NOx) emissions of a partially premixed flame were investigated experimentally.

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, Volume 57, Issue 10, Page 1644-1653, October 2026.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO 2 and the v2 mode of CH 4. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH 4 and CO 2 spectra in a diffusion flame.
