N2 - Photo-visualization measurements in an argon flow served to determine the influence of large van der Waals clusters on the transverse dimensions of a supersonic under-expanded jet. In the range of average sizes of formed clusters 330 < 〈S〉 > 6200 part./clust., a model of corrections to the known gas-dynamic empirical dependences, formed in the absence of a condensed phase, was proposed to take into account the features of gas outflow from a supersonic nozzle under developed condensation. The possible reasons for the broadening of gas flows with developed condensation were established. The proposed correction model was tested in supersonic outflows of condensing gas on a number of supersonic conical nozzles.
