An experimental investigation of fuel spray vapor phase characterization
An experimental study of an infrared laser extinction technique for measuring fuel vapor flux in evaporating liquid fuel sprays was conducted. The infrared laser extinction technique consists of three separate measurements: a visible light angular scattering measurement, a visible light …

Experimental and Numerical Studies on the Soot Formation of Liquid Fuel Relevant Compounds
… improved data analysis approach for the combined laser extinction and two-angle elastic light scattering diagnostics to relate the various measured optical cross sections to soot aggregate properties. Compared to previously reported studies, the proposed approach can be applied to a wider range of …

Experimental investigation of constant volume sulfur dust explosions
… regime of sulfur dust ames. A two-dimensional laser extinction technique was used to characterize the powder dispersion and uniformity by measuring the particle concentration with spatial and temporal resolution. The two-dimensional measurement provided a methodology to increase the number of …

Continuous DPM Monitoring in Underground Mine Environments: Demonstration of Potential Options in the Laboratory and Field
… decision making. The monitor works on a laser extinction principle to measure EC, the black component of DPM, as mass accumulates on a filter. The Airtec has proven useful for personal monitoring and short-term DPM surveying. However, capabilities are needed for continuous, long-term …

Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications
Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane …
