Özet
An experimental set-up is developed to investigate the burning of levitated aluminum particles ignited by a CO2 laser:n air under high pressure conditions Residence times of aluminum particles burning in the eieccrodynamic levitator arc long enough to observe the total burning process, under low and high pressures. Experiments allow to measure the ignition delay and the burning times of aluminum panicles. Brightness temperatures arc also measured. These measurements and the accompanying high speed -mages give useful information on the burning processes of aluminum panicles under various regimes A numerical model is also developed to predict aluminum particles’ burning rates and the sizes of the alumina residues.
