Abstract
The boiling in a superheated water jet discharged from a short cylindrical nozzle in the presence of a passive swirler has been experimentally investigated. The evolution of the disintegration of the boiling liquid jet with an increase in the degree of superheating has been studied. Characteristic structures and forms of the flow have been identified. The correlation between the jet shape and boiling regimes has been found. Significant fluctuations and flow instability at certain temperatures was noted. The possibility of influencing the flow pattern has been experimentally shown.
