1. 21. Laser-Plasma Sources for Extreme-Ultraviolet Lithography

   Författare :Björn Hansson; KTH; []
   Nyckelord :fluid and plasma; radiation; electronics; electrical;

   Sammanfattning : This thesis describes the development and characterizationof a liquidxenon- jet laser-plasma source forextreme-ultraviolet (EUV) radiation. It is shown how thissource may be suitable for production-scale EUV lithography(EUVL). LÄS MER

3. 22. Large Eddy Simulation of Complex Turbulent Flows

   Författare :Magnus Berglund; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; fluid dynamics; plasmas; Computational Fluid Dynamics CFD ; Large Eddy Simulation; Complex Turbulent Flows; plasma; Gaser; fluiddynamik;

   Sammanfattning : This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. LÄS MER

4. 23. Membrane emulsification: modelling interfacial and geometric effects on droplet size

   Författare :Marilyn Rayner; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

   Sammanfattning : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. LÄS MER

5. 24. Experimental Studies of Separated Flow and Heat Transfer in a Ribbed Channel

   Författare :Lei Wang; Värmeöverföring; []
