Soot optical diagnostic laboratory

Infrastruktur

    Information

    Beskrivning

    The laboratory works with development and application of optical and laser diagnostic methods to study soot particles. The work includes technique development, studies of soot formation phenomena, and applied diagnostic measurements on lab scale as well as in practical devices. Projects include studies of optical properties of soot, soot formation in diesel engines and gasifiers. Fundamental soot formation and fuel conversion investigations are made on biomass particles. Optical diagnostic methods are supported by sampling techniques combined with alternative detection techniques such as transmission electron microscopy (TEM). The main laser diagnostic methods are elastic light scattering, extinction, laser-induced fluorescence, laser-induced incandescence, and Raman scattering.
