Abstract

A series of experimental studies of the boiling liquid flow from holes of 8-60 mm diameter were conducted. The initial water pressure in the tank was 7-11.5 MPa, water temperature was 160-235℃. Various stages of jet formation were determined as well as the jet out flowing velocity, and velocity of the flow. An quasi-stationary model of boiling liquid flow was suggested. The estimated data on the density distribution of the vapor-liquid mixture in the jet were given.
