Аннотация:A gas dynamic model of supersonic expansion of a real (supercritical) gas flow in nozzle based
on the Redlich-Kwong equation of state has been developed. The proposed model can serve as a
basis for describing the expansion of the main gas (carrier gas), against which processes of
interest (formation of clusters, microcapsules, condensation) occur. Specific calculations were
performed for clustering in Ar and Kr flow. Experimental verification of results of the model
calculations of the sizes and densities of Ar and Kr clusters using the Rayleigh scattering method
was performed. The proposed model for describing cluster jets has been tested in the experiments
aimed at creating X-ray sources and accelerated electron beams in the process of relativistic laser
action on a krypton cluster jet.
