A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

Energy Science &Engineering, Volume 14, Issue 6, Page 2897-2929, June 2026.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

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

Fluids, 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 ...

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

Energy Science &Engineering, Volume 14, Issue 6, Page 3028-3041, June 2026.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

Measurement and Identification of Flame Describing Function (FDF) Based on Parallel Subsystem Model

Aerospace
Because of the need for low pollutant emissions, industrial gas turbines typically use partially premixed gases for combustion. However, the nonlinear dynamic characteristics of partially premixed flames have not been studied sufficiently.

Flame structure simulation in a methane/air coflow partially premixed burner

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
The effect of the equivalence ratio on the partially premixed methane / air laminar flame structure, in a coflow atmospheric burner was simulated. Three equivalence ratios were studied (Φ=1.6, Φ=2.0, Φ=3.5) keeping constant the released energy.
