Abstract:
Experimental results of the outflow of ethanol microjets from the capillary (vertical flow in the direction of gravity) and from the hole in the wall (in the horizontal direction) are presented. It is shown that a long-term flow of a microjet of a liquid in a vacuum exhibits a high degree of instability with sudden changes in direction, structure, observed density and differs significantly from the well-studied modes of outflow into the atmosphere, as well as from short-term modes of outflow into vacuum. The main features of the flow and the conditions for the onset of instability are described. A probable explanation of the reasons for the destruction of the microjet is given.
Keywords:
microjet of liquid, barocapillary instability of flows, modeling of vacuum conditions, ethanol.
