ABSTRACT

An experimental investigation of the ignition and combustion phenomena of laser-ignited aluminum agglomerate at elevated pressures is presented. Aluminum agglomerates of nominal diameters of 535 μm were ignited by a focused CO2 laser pulse in a quiescent environment of O2/N2 (20/80) at different ambient pressures ranging between 0.1 and 4.3 MPa. A two-color Pyrometer and a broad band radiometer were employed to measure the surface temperature and the radiation emitted by the burning aluminum agglomerate, respectively. Using the outputs of the two-color pyrometer and the broad band radiometer, the ignition temperature, the ignition delay time and the burning time were obtained. A high speed camera was used to observe the phenomenological events during the burning of the aluminum agglomerate, and to correlate with the results obtained from the pyrometer and radiometer.
