2. 1. Characterization of Gasoline Spray-Wall Interactions

   Author : Ronny Lindgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Phase Doppler Anemometry PDA ; gasoline sprays; wall film; modeling; experiments; Computational Fluid Dynamics CFD ; spray-wall interaction;

   Abstract : Interest in spray-wall interactions has intensified recently because of the development of direct injection spark ignition engines. In this type of engine, impingement of the spray on the piston and cylinder walls leads to increased emissions of hydrocarbons and soot. READ MORE

4. 2. Laser Sheet Imaging and Image Analysis for Combustion Research

   Author : Rafeef Abu-Gharbieh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

   Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

6. 4. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

   Author : Magnus Marklund; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. READ MORE

7. 5. Exposing the Exposures : Assessing occupational aerosol exposures and their possible health and toxicological effects
