In this study, we experimentally investigate large-scale vortex structures, fuel-air mixing and reaction processes, which occur in a partially premixed swirl-stabilized ethylene/air flame in …

Large-eddy simulations of a sooting aero-engine model combustor are performed for three operating points. They are analyzed to investigate the influence of secondary air injection …
The relationships between flow field, flame structure, and soot distribution were investigated experimentally in turbulent 4 kW non-premixed swirl flames of methane and air at three …
Swirl-stabilized turbulent spray flames operating at atmospheric pressure, with both a conventional Jet-A kerosene ('A2') and a synthetic fuel blend ('C5') and radially-injected …

Abstract Non-volatile Particulate Matter (nvPM) from aircraft gas turbine engines are harmful to both human health and the environment, but can be significantly reduced by using low …
Soot formation and oxidation in a turbulent n-heptane jet spray flame are investigated through simultaneous imaging of quantitative soot volume fraction (fv), flame-front (OH), and …
Abstract This work uses Large Eddy Simulation (LES) combined with an accurate chemical description to predict soot formation in a turbulent spray flame burning real fuel at …
Global instabilities in swirling flows can significantly alter the flame and flow dynamics of swirl-stabilized flames, such as those in modern gas turbine engines. In this study, we …
Soot formation at lean-threshold conditions referred to as “near-threshold sooting conditions”(ie, with stoichiometry, φ, around 1.90 for ethene as a fuel) are studied in laminar …
