HOLOGRAPHIC INVESTIGATION OF MICROEXPLOSION IN AN EMULSIFIED DIESEL OIL SPRAY
ABSTRAKT
In this article an experimental study is reported on the atomization and vaporization characteristics of pure and emulsified diesel oil sprays in a high-temperature bomb. Fraunhofer holography was utilized to collect the necessary experimental data. The emulsified oil spray exhibited better atomization characteristics than the pure ой spray. Droplet fragmentation was observed in the emulsified oil spray, and this is attributed in part to the distinct phase boundaries present in the emulsion and in part to the puffing of vaporizing water in a high-temperature environment. For a spray created with a pintle diesel nozzle, it was found that the droplets of the outer spray region art larger than the droplets of the inner spray region, more so in a low-temperature environment.
