Influences of Dual Air-Swirler Angles on Swirling Injection and Combustion of Kerosene-Air at a Supercritical Pressure

Aerospace Research Communications
High-pressure swirling injection and combustion are important phenomena in a modern gas turbine engine as its compression ratio has been significantly increased to improve thermodynamic efficiency.

NASA/Pratt and Whitney experimental clean combustor program: Engine test results [PDF]

, 1977
A two-stage vorbix (vortex burning and mixing) combustor and associated fuel system components were successfully tested in an experimental JT9D engine at steady-state and transient operating conditions, using ASTM Jet-A fuel. Full-scale JT9D experimental

Fuel-injector/air-swirl characterization [PDF]

The objectives of this program are to establish an experimental data base documenting the behavior of gas turbine engine fuel injector sprays as the spray interacts with the swirling gas flow existing in the combustor dome, and to conduct an assessment ...

Numerical Study on the Self-Pulsation Characteristics of LOX/GH2 Swirl Coaxial Injector

International Journal of Aerospace Engineering
To investigate the self-pulsation characteristics of a liquid-centered swirl coaxial injector with liquid oxygen (LOX) and gas hydrogen (GH2) as the working mediums under supercritical condition, a numerical simulation was employed.

Experimental study of the spray characteristics of a research airblast atomizer [PDF]

Airblast atomization was studied using a especially designed atomizer in which the liquid first impinges on a splash plate, then is directed radially outward and is atomized by the air passing through two concentric, vaned swirlers that swirl the air in ...

Flash boiling effect on swirled injector spray angle

, 2002
Abstract A swirled injector for gasoline direct injection was used to investigate the effect of fuel flash boiling on the initial angle of the spray. The hollow cone spray was injected into a constant pressure bomb filled with quiescent air. The fuel was fed at 7 MPa constant pressure to the injector.
