Abstract
To study the thermal microstructure of the SHS wave, a high-speed micropyrometric complex for measuring temperature and flame propagation velocity was assembled. Experimental studies of the spatiotemporal development of the SHS combustion wave in powder mixtures of the Ni-Al system were carried out using high-speed filming. Based on the data obtained, the characteristic spatio-temporal scales of the thermal structure of the SHS wave and the temperature dynamics at a local point were determined. The study of the dynamics of the thermal microstructure in the reaction region at later times showed that the reaction proceeds in the spin combustion mode, since in this case, the particles are sequentially ignited from each other. Quantitative statistical processing of the brightness temperature fields showed the presence of short-lived centers with superadiabatic brightness temperatures, also reaching 1760 ℃. Comparison of video frames of the combustion process in high-temperature regions and the corresponding areas on the frames of the bulk and reaction products confirms that the majority of high-temperature centers is located in pores or is in direct contact with them. Therefore, further research is needed to introduce a correction factor for a more accurate measurement of brightness temperature.
