Paper Abstract

This paper presents the results of study devoted to the laser speckle imaging method application for characterizing the combustion of aluminum nanopowder in air. The experimental schema is introduced for the combustion process characterization. The main advantage of speckle imaging is the ability to study the surface of the burning sample despite high-temperature bright glow. Analysis of the image correlation coefficient allows us to obtain the temporal parameters of the burning sample surface changes. The experiments have shown the applicability of the method of speckle imaging of combustion processes study.
