Abstract:

This paper presents a method for recording and processing the images of the tracks of self-luminous fast-moving particles in high-temperature gas flows, based on the use of a domestically manufactured high-speed digital camera with a Nanogate-2 array photodetector having 10-ns temporal resolution. Specially developed software was used to process the experimental data obtained on the test stand of the N. É. Bauman Moscow State Technical University to investigate supersonic spray-coating. The radial distributions of the particles over velocities and concentrations are found, along with their temporal and statistical characteristics, which are needed to estimate how efficiently such flows act on the surface being processed.
