N2 - Experimental results of observation of ethanol and propylene glycol microjets flowing into a highly rarefied medium (vacuum) through a nozzle are presented. The study of the outflow process was carried out both for horizontal and vertical outflow of liquid from the source in the direction of gravity. The condition was met for maintaining the residual gas background pressure in the discharge chamber much lower than the saturated vapor pressure of the working fluid at the selected discharge temperature. It is established that the flow from a thin capillary or small-diameter nozzle into a vacuum or highly rarefied gas medium differs significantly from the well-studied flow modes into a dense gas medium. It is shown that in all studied regimes the fluid flow is statistically unstable, with a large number of sudden changes in direction, structure, and observed density. The paper describes the main features of such a flow and the conditions for the onset of instability.
