Cryogenic and Simulated Fuel Jet Breakup in Argon, Helium and Nitrogen Gas Flows

摘要

Two-phase flow atomization of liquid nitrogen jets was experimentallyinvestigated. They were co-axially injected into high-velocity gas flows of helium, nitrogen and argon, respectively, and atomized internally inside a two-fluid fuel nozzle. Cryogenic sprays with relatively high specific surface areas were produced, i.e., ratios of surface area to volume were fairly high. This was indicated by values of reciprocal Sauter mean diameters, RSMD's, as measured with
