Spray Structure in Near-Injector Region Of Aerated Jet in Subsonic Crossflow (Postprint)
Abstract
An experimental study of the breakup of aerated liquid jet in subsonic crossflow was carried out. The test conditions were as follows: jet exit diameter of 1 mm, GLR (gas to liquid ratio) of 8%, and jet-to-free stream momentum flux ratio of 0.74. Digital double-pulsed holograms were recorded at x/do = 0 to 25 in the cross stream direction, y/do = 0 to 27 in the stream wise (injection direction), and z/do = (-13) to 13 in the span-wise direction. Digital double-pulsed holographic microscopy (DHM) was utilized using double exposure 2048x2048 pixels CCD sensor. The field of view of all holograms was 9 mm x 9 mm, and the spatial resolution was 5 m. To overcome this small field of view, three-dimensional spray maps were constructed by patching several high resolution holograms. Measurements include droplets locations, drop sizes and sphericity, and three-dimensional velocities. The distributions of the drop sizes could be fully described by the SMD alone and followed Simmons' universal root-normal distribution.
