    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

  2. 7. Investigations of Diesel Sprays in Optical Engines - Liquid Fuel Penetration and Lift-Off Length

    Author : Guillaume Lequien; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed imaging; liquid penetration; lift-off length; soot; optical engine; Diesel sprays;

    Abstract : Diesel engines are widely used as powertrain solutions for transportation vehicles. Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment.

  3. 8. The Influence of Multiple Injections on Combustion : an Experimental Investigation

    Author : Rickard Ehleskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple injections; direct injected DI diesel engines; diesel sprays; emissions; Internal combustion engines; diesel combustion;

    Abstract : The high fuel efficiency and torque of the diesel engine has made it the obvious choice for heavy duty applications for a long time. In addition, these characteristics of the modern super-charged HSDI diesel engine also make it very suitable and popular for car applications. READ MORE

  4. 9. 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

  5. 10. Numerical Studies of Methanol PPC Engines and Diesel Sprays

    Author : Mateusz Pucilowski; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Partially Premixed Combustion PPC ; spray-wall interaction; piston geometry; multiple injections; ICE; ignition front; diffusion flame; combustion mode; RANS; LES; PPC; Diesel spray;

    Abstract : The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). READ MORE
