Description

Laser diagnostic techniques are used to investigate pyrolytic, oxidative, aerodynamic, and heat transfer processes associated with determining optical, physical, and chemical properties of materials. Applications include characterization of atmospheric particles, liquid droplets, and ice formation processes for climate change (optical properties), air quality, forensics (trace materials, drugs, explosives), health care (inhalation technology), biofuel, and biomass energy research. Techniques used include phase Doppler interferometry, laser-induced incandescence and fluorescence, gas chromatography/mass spectroscopy, and flow visualization techniques. One developing experimental arrangement includes a rapid laser-heating system (laser-driven thermal reactor) and acoustic levitator. Another arrangement includes an optical system for particle imaging. Computational models, using software packages (e.g., COMSOL) available at NIST, are also developed for the different processes under investigation.
