N2 - Ground-based simulation of processes around space vehicles in open space is an issue for rocket industry. Some problems can be covered by mid-size vacuum-based gas-dynamic setups; they provide the model flow regimes for imitation of natural regimes and can be beneficial due to low financial and material costs. The updates for the laboratory vacuum facility LEMPUS-2 based in Novosibirsk State University and improvements in gas dynamic diagnostic tools enabled to expand the range of modeling supersonic jets emerging from nozzle blocks. This paper presents the measurement results performed for binary cluster jets using photo visualization method and scanning of argon flows for different ratios of stagnation pressure to ambient pressure. The process of condensation has a significant influence on the dynamics of interacting jets.
