Electrophoresis‐Enhanced Delivery of Rhamnolipid‐Coated Ozone Micro‐Nano Bubbles for Remediating Heterogeneous Aquifer

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Remediating organic pollutants in heterogeneous aquifer presents a significant challenge due to the limited penetration of chemical reagents into these zones. Ozone micro‐nano bubbles, with their small diameters, can transport to low‐permeability zone (LPZ) and oxidize target contaminants; however, their mobility is often hindered by ...

Simulation of Nonpremixed Jet Flame Using Flamelet‐Generated Manifold

Safety Science and Technology, Volume 1, Issue 1, March 2026.
A flamelet‐generated manifold (FGM) approach is proposed and validated by nonpremixed methane jet flames. The effects of radiation and buoyancy were critically examined, and nonpremixed and premixed tabulation methods were compared, revealing the importance of radiation, buoyancy, and appropriate flamelet prototype in accurate FGM modeling.

Soot Formation Mechanisms in Ethylene/N2O Inverse Diffusion Flames: Insights From Dual‐Wavelength LII and SEM Analysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Nitrous oxide (N2O), with its self‐pressurizing capability, strong oxidizing potential, and exothermic decomposition, is considered a promising green propellant oxidizer. However, when combined with hydrocarbon fuels, the concurrent formation of soot and polycyclic aromatic hydrocarbons (PAHs) remains a major challenge for propulsion efficiency and ...

Extinction characteristics of ammonia/air counterflow premixed flames at various pressures

Journal of Thermal Science and Technology, 2016
Ammonia has promising features as a carbon-free fuel without greenhouse gas emission. However, due to its low combustion intensity, the combustion characteristics of ammonia have been rarely investigated.

Numerical Study on the Influence of CO2 Dilution on Soot Emission in Turbulent Diffusion Flames Impinging on a Cold Surface

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
A flame impinging on a cold surface, frequently utilized in engineering applications, produces a greater amount of soot, which affects health and environmental impacts. The CO2‐diluted turbulent nonpremixed flame impinging on a cold surface is computationally investigated because it is one of the common techniques for reducing emissions.

An Experimental PIV/POD Study on the Sequentially Coupled Flow Field of Swirl and Multiple Jets

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
The stepwise flow reconstruction induced by sequential coupling of swirl, primary jets, and dilution jets was experimentally investigated in a model combustor using high‐speed PIV and proper orthogonal decomposition (POD). Three nonreacting configurations were compared: pure swirl, swirl plus primary jets, and swirl with both primary and dilution jets.
