In this paper, we present results from spontaneous ignition of aluminium particle clouds in a series of shock tube experiments. For all experiments, the shock propagates along a narrow pile of 40- \upmu m aluminium particles. The study includes shock Mach numbers in the range from 1.51 to 2.38. See more Pressure sensors are mounted in the ceiling of the driver, driven, and window sections, with their distances given relative to the left-hand driver wall (Table 1). … See more For all 30 experiments, approximately 1000 images are generated from each of the two high-speed video cameras. This leaves an extensive amount of data to be … See more The second high-speed video camera is used as a dark-film camera to capture the particle ignition and burning. The dark-film setup uses an exposure time of … See more Web1 Jul 2003 · In this work it is assumed that aluminum particles are ignited as their temperature reaches the melting point of aluminum and all of the aluminum of particles …
