Simultaneous imaging of soot volume fraction, PAH, and OH in a turbulent n-heptane spray flame
Combustion and Flame, 2019 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 soot-precursor marked by smaller (2–4 ring) polycyclic aromatic ...

High spatial resolution laser cavity extinction and laser-induced incandescence in low-soot-producing flames [PDF]
, 2015 Accurate measurement techniques for in situ determination of soot are necessary to understand and monitor the process of soot particle production. One of these techniques is line-of-sight extinction, which is a fast, low-cost and quantitative method to ...

Two-dimensional imaging of soot volume fraction in laminar diffusion flames
Applied Optics, 1999 A technique for acquiring two-dimensional soot-volume-fraction measurements in laminar flames has been demonstrated. The technique provides a map of very low noise concentration over a range of wavelengths (250-1100 nm). A noise level of 0.0007 in extinction and a spatial resolution of 30-40 microm for soot concentration were achieved with an arc lamp ...

Determination of the volume fraction of soot accounting for its composition and morphology
, 2020 The soot volume fraction, fv, is essential for combustion engineering, air quality and climate modeling. It is commonly obtained from mobility or optical data assuming soot spheres of constant composition that tend to overestimate fv by up to an order of

Trends in Ocean S‐Isotopes May Be Influenced by Major LIP Events
Geophysical Monograph Series, Page 341-376., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
