  4. 2. Experimental Studies of Primary Break-up of Diesel Engine Fuel Injector Sprays

    Author : Zachary Falgout; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water sprays; Sprays; Turbulence; Transparent injectors; Diesel engines; Cavitation; Primary break-up; Orifice flow; Multiphase flows; Transcritical fluids;

    Abstract : This thesis will focus on experimental studies of primary breakup of pressure-atomized sprays. The industrial application that this thesis will address is fuel sprays in modern Diesel engines, and so the focus will be sprays emitting into relatively slow-moving, high pressure, high-temperature gases.

    Author : Holger Grosshans; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomization; Multiphase Flows; Jets; Sprays; Large Eddy Simulation;

    Abstract : Liquid-gas two-phase flows occur frequently in daily life, in nature e.g. falling rain drops or waves in the sea, and in industrial applications, e.g. READ MORE

  6. 4. Temporally gated imaging for investigation of atomizing sprays

    Author : Mattias Rahm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ballistic imaging; Imaging through turbid media; Sprays; Velocimetry; Time-gated sectioning.; Optical Kerr effect; Ultrafast lasers;

    Abstract : Fuel sprays play an important role in the combustion process of modern compression ignition engines, but their dynamics are not well understood. This thesis focuses on time-gated imaging techniques as a means to study the optically dense spray formation region of these atomizing sprays. READ MORE

  7. 5. Interior Flow and Formation of Plain Orifice Sprays

    Author : Zachary Falgout; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ballistic Imaging; Sprays; Fluid Mechanics; Mixture Formation;

    Abstract : This thesis will summarize recent experimental observations of spray formation in highly atomizing plainorifce sprays, the kind commonly produced by fuel injectors in compression ignition internal combustionengines. Two special interactions will be addressed in detail: primary atomization under elevated ambientpressures and temperatures and orifce ow effects on primary atomization. READ MORE
