The spectral study results of a supersonic clustered argon flow stimulated emission in the region of particle excitation (on an electron beam) and downstream are presented. Anomalies in the luminescence of the traditional spindle-shaped jet and the flow of heavy clusters (“wake”) are discussed. Possible causes of the observed anomalous phenomena are presented on the basis of the given comparisons of the results obtained.

The role of condensation on the shape and size of a supersonic argon stream flowing from a nozzle into a rarefied space is considered. It is shown that with the growth of cluster sizes, both the primary "traditional" supersonic jet and the external cluster flow formed when heavy clusters penetrate through the lateral compressed layers of the primary flow into the surrounding background gas increases. The type of correction factor in the well-known empirical formula proposed by Ashkenas and Sherman is found, taking into account which this formula can be used in conditions of clustered flows. The reasons for the impact of clusters on the gas dynamics of supersonic flow, conditions and limitations of such an effect are discussed.

“…The study was performed at the gas dynamic vacuum bench LEMPUS-2 of the Novosibirsk State University. The bench has been described in details in [6], the schematic diagram of measurements during the liquid outflow is given in [7]. Observation, photographic work and video (blackand-white) recording of the studied liquid microjet in the mode of continuous outflow from a thin capillary or smallsize aperture in a flat wall were performed through optical windows.…”

The paper presents experimental results on ethanol microjets outflow from a capillary (vertical flow by gravity) and from a hole in the wall (horizontal flow). The long-term liquid microjet flowing into vacuum has been shown to be highly unstable with sudden changes in direction, structure and observable density and essentially differing from well-studied modes of outflow into the atmosphere as well as from the modes of short-term outflow into vacuum. The main specific features of the flows and conditions giving rise to instabilities are described. Possible explanation of the reasons for microjet destruction is given. Keywords: liquid microjet, barocapillary instability of flows, modeling of vacuum conditions, ethanol.
