High Temperature Combustion

The paper is devoted to development of methods for studying the dynamics of high-temperature combustion of aluminum nanopowder.The difficulty in studying the combustion of nanopowders is the high temperature and intensity of light emissionduring the combustion process, which makes the visual observation virtually impossible.The paper discusses various schemes using laser radiation to study the combustion processes of metal nanopowders.Particular mentions the use of the laser monitor based on an active medium on copper bromide vapor to study the combustion process of various powders and mixtures.The laser monitor combines the functions of the narrow-band laser illuminator and the brightness amplifier, thereby achieving the visualization at a narrow gain wavelength. Therefore, the laser monitor can be used to observe the changes in the surface of a burning sample with high temporal and spatial resolution.

High Temperature Combustion

A laser monitor with two image acquisition channels based on two brightness amplifiers and two digital cameras is presented. The laser monitor makes it possible to visualize the surface of metal nanopowders during combustion simultaneously in two regions of the sample or in one region with different magnifications. The delay between the radiation pulses of the brightness amplifiers is set in such a way that the radiation of one brightness amplifier does not affect the image formed by the other brightness amplifier. The proposed experimental technique makes it possible to study the surface of samples of powder materials during high-temperature combustion, accompanied by intense glowing and scattering of combustion products. The use of two-channel visualization makes it possible to study the surface of a burning sample in more detail, in particular, to study the inhomogeneity of the combustion process.
