A web-based interface for modeling laser-induced incandescence (LIISim)

چکیده
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 groups.

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 کاملLaser-induced incandescence for soot particle size measurements in premixed flat flames.
Measurements of soot properties by means of laser-induced incandescence (LII) and combined scattering-extinction were performed in well-characterized premixed ethylene-air flames. In particular, the possibility of using LII as a tool for quantitative particle sizing was investigated. Particle sizes were evaluated from the temporal decay of the LII signal combined with heat balance modeling of l...
