Experimental Study on Laminar Burning Velocity and Flame Instability of Liquefied Petroleum Gas/Dimethyl Ether Blended Gas: Effects of Equivalence Ratio and Blended Ratio

Safety Science and Technology, Volume 1, Issue 3, September 2026.
This study reveals the regulatory effect of LPG addition on laminar burning velocity of DME/air mixtures, and elucidates the governing mechanisms of flame instability under varying initial conditions. ABSTRACT Liquefied petroleum gas/dimethyl ether (LPG/DME) blended gas is a promising clean alternative fuel, characterized by high efficiency and clean ...

Numerical Investigation of an OxyfuelNon-Premixed CombustionUsing a Hybrid Eulerian Stochastic Field/Flamelet Progress Variable Approach: Effects of H₂/CO₂Enrichment and Reynolds Number

Energies, 2018
In the present paper, the behaviour of an oxy-fuel non-premixed jet flame is numerically investigated by using a novel approach which combines a transported joint scalar probability density function (T-PDF) following the Eulerian Stochastic Field ...

Humidity‐Enhanced Chemoresistive Sensor Performance in a p‐Type Spinel Metal Oxide

Small Structures, Volume 7, Issue 9, September 2026.
Humidity reduces the performance of most chemoresistive metal–oxide gas sensing. Here, we demonstrate humidity‐enhanced acetone sensing with ZnMn2O4 by utilizing surface hydroxyl groups. Combining in situ DRIFT spectroscopy and isotope labeling, this work reveals that hydroxyls actively promote analyte oxidation, offering a new strategy to improve ...

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, Volume 38, Issue 43, 3 August 2026.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3970-3983, August 2026.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Experimental Study on Bluff-Body Stabilized Premixed Flame with a Central Air/Fuel Jet

Energies, 2017
Bluff-body flame holders are commonly employed in many industrial applications. A bluff-body is usually adopted to enhance the downstream mixing of the combustion products and the fresh fuel-air mixtures, thus to improve the flame stability and to ...
