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 ...

Numerical Study of a Direct Injection Internal Combustion Engine Burning a Blend of Hydrogen and Dimethyl Ether

Drones, 2018
In the reported study, various aspects of dimethyl ether/hydrogen combustion in a Reactivity Controlled Compression Ignition (RCCI) engine are numerically evaluated using Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES).

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.

Sustainable Flame Retardant System with Thermomechanically Modified Stinging Nettle Tailored for Polyamide 12

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
A sustainable flame retardant system for polyamide 12 is developed by combining melamine polyphosphate with thermomechanically modified stinging nettle. The plant‐derived component alters degradation pathways, enhances char formation, and reduces heat release.

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced

Siloxane Decomposition and Clustering in Atmospheric Pressure Non‐Thermal Plasma Discharge

Plasma Processes and Polymers, Volume 23, Issue 6, June 2026.
Atmospheric‐pressure He/HMDSO plasmas convert HMDSO to PDMS deposits. At lower power, mass growth is suppressed, while small silicon‐containing fragments and hydrocarbon radicals dominate. Stable small hydrocarbons are formed at higher power, reflecting enhanced fragmentation and recombination pathways.

Effects of Partial Premixing and Coflow Temperature on Flame Stabilization of Lifted Jet Flames of Dimethyl Ether in a Vitiated Coflow Based on Stochastic Multiple Mapping Conditioning Approach

Fluids
The Reynolds-averaged Navier–Stokes (RANS)-based stochastic multiple mapping conditioning (MMC) approach has been used to study partially premixed jet flames of dimethyl ether (DME) introduced into a vitiated coflowing oxidizer stream.

Control of the low-load region in partially premixed combustion

Journal of Physics: Conference Series, 2016
Partially premixed combustion (PPC) is a low temperature, direct-injection combustion concept that has shown to give promising emission levels and efficiencies over a wide operating range. In this concept, high EGR ratios, high octane-number fuels and early injection timings are used to slow down the auto-ignition reactions and to enhance the fuel and ...
