APPLIED LASER SPECTROSCOPY IN TECHNICAL COMBUSTION SYSTEMS

Several laser-based diagnostic techniques for nonintrusive measurement s of species concentrations and temperatures were developed during rec ent years and have become valuable tools to study technical combustion processes. Data gained from such experiments are the basis for a comp arison with detailed mathematical modelling of chemical processes in l aminar and turbulent flows including heat and species transport. Examp les for the application of laser-induced fluorescence (LIF), laser-ind uced thermal grating spectroscopy (LITGS), Rayleigh scattering (RS), d ifferential absorption (DIAL) and emission in the infrared in ignition processes, internal combustion engines, municipal waste incinerators, and pressurized fluidized bed reactors are described.
