Soot temperature and volume fraction field predictions via line-of-sight soot integral radiation equation informed neural networks in laminar sooting flames

Physics of Fluids
This paper originally proposes a physics informed neural networks (PINNs) model for the simultaneous prediction of soot temperature and volume fraction fields in laminar flames from experimental soot integral radiation. Contrasted with the previous data-driven models, the PINNs model incorporates the line-of-sight soot radiation integral equation into ...

Influence of soot self-absorption on simultaneous 3D temperature and soot volume fraction measurements in turbulent flames

Optical investigations of turbulent sooting flames present multiple challenges, one of which is soot self-absorption (SSA), where part of the radiation signal is absorbed by the flame itself before reaching the detector. The present paper adapts an approach from the literature applied to a laminar axisymmetric flame to correct effects of SSA in a ...

Soot Volume Fraction and Particle Size Measurements using Laser-Induced Incandescence

Soot is a byproduct formed during incomplete combustion of hydrocarbon fuels. Atmospheric soot from aircraft emissions increases local air temperatures, drives cloud formation, and decreases albedo on snow and ice: three factors that promote global warming.
