Formation and Evaporation of Near-Wall Liquid Films Under Expansion from a Nozzle Into Vacuum

Expansion of near-wall liquid films with different physical properties accompanied by high-velocity co-current gas flow from a nozzle into vacuum is studied experimentally. Local parameters of liquid films inside the nozzle are measured. Gas-droplet flow structure behind the nozzle exit cross-sectio...

Zusammenfassung:	Expansion of near-wall liquid films with different physical properties accompanied by high-velocity co-current gas flow from a nozzle into vacuum is studied experimentally. Local parameters of liquid films inside the nozzle are measured. Gas-droplet flow structure behind the nozzle exit cross-section is examined. Limiting temperatures of liquid films formed on the outer surface of the nozzle are measured.
