Jin, Seong-Ho and Brear, Michael and Zakis, George and Watson, Harry and Carlisle, Hugh (2005) Effect of chamber pressure on the spray from an air-assisted, direct fuel injector. In: 5th Asia-Pacific Conference on Combustion, 17-20 July 2005, University of Adelaide.

The transient behaviour of the fuel spray from an air-assisted fuel injector has been investigated experimentally in a constant volume chamber (CVC), whilst varying the chamber pressure. Ensemble averaged, planar images of the laser induced fluorescence (LIF) and Mie scattering from the spray have been obtained, as well as back-illuminated images. The effect of the ambient pressure on the spray penetration of the air-assisted fuel injector is determined. Unlike conventional single-phase injectors, large vortex structures are observed, indicating that the air and liquid motion are strongly coupled. These results also show that the spray penetration varies significantly with chamber pressure.
