Features of formation of a fluid flow flowing into a highly rarefied medium through a capillary

Research output: Contribution to journalConference articlepeer-review

Abstract

Experimental results of investigation of the form and structure of the flow of ethanol and propylene glycol into a highly rarefied medium (vacuum) through a capillary are presented. It is shown that when liquid flows vertically along gravity into a vacuum with a pressure of residual gases significantly less than the pressure of saturated vapors at the outlet temperature, the liquid jet, in contrast to the flow into a dense gas medium, is statistically unstable, subject to bending deformations and explosive spray.
