••
TL;DR: In this article, the initial and bright-spot diameters of the aluminum particle are measured directly from the images by using the in-house automated data processing routines, and the results suggest that with the goal of decreasing the total time, suitable methods can be employed for different conditions.

••
TL;DR: In this paper, a high-speed camera with a high magnification zoom lens was used to record the changing processes of aluminum wires, droplets and flames, and the spectrum distribution of the flame was also registered by an optical spectrometer.
33 citations
••
TL;DR: In this paper, a series of experimental conditions with different oxygen contents and temperatures was designed to examine their effects on the ignition and combustion times of single-alloy particles, and the particle sizes, ignition delay times, combustion times, and total times were measured synchronously using a two-camera system.
27 citations
••
TL;DR: In this paper, the effects of ambient temperature on the ignition and combustion process of single aluminium particles (40-170μm) were examined, and it was shown that the particle ignition probability is very sensitive to the ambient temperature.

••
TL;DR: In this article, the evaporation process of a single kerosene gel droplet can be divided into three stages, i.e., the stage of evapuration of kerosenes, stage of gellant layer formation, and stage of the swell of the gellants.
