Dispersed-phase structure of pressure-atomized sprays at various gas densities

Effects of Ambient Gas Density on the Structure of Pressure-atomized Sprays

A theoretical and experimental study of the dense-spray region of pressure-atomized nonevaporating sprays is described, emphasizing effects of ambient gas density in the atomization breakup regime. Mean liquid volume fraction distributions were measured for 9.5 mm diameter water jets in still air at pressures of 1-8 atm. Mixing was strongly affected by the gaslliquid density ratio and the degre...

Continuous-phase Properties of the Near-injector Region of Non- Evaporating Pressure-atomized Sprays

Qualitative measurements of pressure-atomized sprays through simultaneous collection of planar fluorescence, phosphorescence, and Mie scattering data

A laser diagnostic technique useful for qualitatively locating and describing regions of vapor and liquid structures of a pressure atomized fuel spray is examined. While Mie scattering is sensitive to the liquid phase within a spray, planar laser-induced fluorescence is sensitive to both the liquid and vapor phases. Hence, a comparison of images utilizing these two techniques could be used to q...

Phase transition and structure of silver azide at high pressure

Silver azide (AgN3) was compressed up to 51.3 GPa. The results reveal a reversible second-order orthorhombic-to-tetragonal phase transformation starting from ambient pressure and completing at 2.7 GPa. The phase transition is accompanied by a proximity of cell parameters a and b, a 3 rotation of azide anions, and a change of coordination number from 4-4 (four short, four long) to eight fold. Th...
