Laser Induced Incandescence and Particle Size
The cooling rate of soot particles after laser induced incandescence (LII) is thought to provide an estimate of the size of nanoparticles (NPs) in the engine exhaust. It is shown that cooling rate is not applicable to NPs, and instead is only a measure of the size of micron-sized particles. The problem is that the conservation of absorbed laser photon energy in NPs is subject to quantum electro...

Laser-Induced Incandescence of Soot at High Pressures Sanaz Ghasemi Master of Applied Science Graduate Department of Aerospace Science and Engineering University of Toronto 2012 Measurements of soot emission properties are of interest in both fundamental research and combustion-based industries. Laser-induced incandescence of soot particles is a novel technique that allows unobtrusive measureme...
متن کاملCharacterization of Carbonaceous Particles by Time-resolved Laser-induced Incandescence
Online-characterization of carbonaceous nanoscaled particles is important in different application fields, e.g., in carbon black production or in automobile raw exhaust. For the determination of mass concentration and primary particle size respectively specific surface area, a possible in situ measurement technique is time-resolved laser-induced incandescence (TIRE-LII). The basic principle of ...
متن کاملLaser-induced incandescence of free and surface-adsorbed particles
The technique of laser-induced incandescence (LII) has been used to study non-soot, in particular silver particles. Experiments were based on experience with LII soot measurements and a sensitivity analysis regarding the influence of various parameters. Some experimental modifications, e.g. double laser pulse excitation, have been tested. A major extension of the LII technique consists in measu...
متن کاملA web-based interface for modeling laser-induced incandescence (LIISim)
In this study we present a model for laser-induced incandescence (LII). Different heat conduction models can be selected and monoor poly-disperse particles can be chosen as well as isolated, single particles or aggregates. We present a web interface that allows the scientific community to directly use this model. This will simplify the comparison of LII models developed by different research gr...
