| Abstract: | Dynamic atomization characteristics of emulsified diesel spray in a combustion bomb was investigated using the single-pluse laser in-line Fraunhofer holographic and high-speed sehlieren photographic technique. A numerical model was developed to describe the drop fragmentation in emulsified oil spray. Good agreement between experimental and calculated results was obtained and a conclusion was achieved that the water in emulsified fuel has a favorable effect on reducing both fuel comsumption and emissions for diesel engines. |
