N1 - The work was supported by the Ministry of Science and Higher Education of the Russian Federation (grant N◦ FSUS-2025-0008) in terms of adapting electron-beam-based visualization tools for complex gas flows, and the Russian Science Foundation (grant N◦ 22-11-00080-П, https://rscf.ru/project/22-11-00080/) in terms of studying the passage of clusters of different sizes through the hanging shocks of a supersonic jet.

N2 - Upgrading the LEMPUS-2 experimental facility at Novosibirsk State University—specifically its vacuum-pumping capabilities and diagnostic tools—enabled a comprehensive investigation of gas outflow from various nozzle blocks. Photographic flow visualization was used to examine interaction features of a two-nozzle block jet at different stagnation-to-ambient pressure ratios, as well as at different spacings between geometrically identical nozzles. The influence of cluster formation on the gas dynamics of the interacting jets was also analyzed.
