1. 6. Dynamic Modelling of Emulsification in High-Pressure Homogenizers

   Författare :Andreas Håkansson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Population Balance Equations; Emulsification; High-Pressure Homogenization; Computational Fluid Dynamics; Mathematical Modelling.;

   Sammanfattning : Different approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended papers to their alternatives and previous suggestions. LÄS MER

3. 7. High Pressure Jet Assistance in Steel Turning

   Författare :Patrik Dahlman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jet Assistance; Tool Life; Chip Control; Turning; Ultra High Pressure Cooling; Jet Momentum;

   Sammanfattning : Steel turning is one of the most common industrial processes today. It is a very old process, where a lot of improvements and optimisations have been done throughout history. But, the struggle for further cost reductions pushes the process development into new areas. LÄS MER

4. 8. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges

   Författare :Louise Andersson; Johan Silfwerbrand; Anders Selander; Ylva Edwards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge maintenance; preventive maintenance; chloride ingress; high-pressure washing; Concrete Structures; Betongbyggnad;

   Sammanfattning : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

5. 9. Experimental Investigations of High Pressure Catalytic Combustion for Gas Turbine Applications

   Författare :Jeevan Jayasuriya; Torsten Fransson; Groppi Gianpiero; KTH; []
   Nyckelord :Gas Turbine Combustion; Catalytic Combustion; High Pressure; Ultra-low emissions; SRA - Energy; SRA - Energi;

   Sammanfattning : This work is devoted to generate knowledge and high quality experimental data of catalytic combustion at operational gas turbine conditions.The initial task of the thesis work was to design and construct a high pressure combustion test facility, where the catalytic combustion experiments can be performed at real gas turbine conditions.

7. 10. Experimental investigation of molecular solids and vanadium at high pressure and temperature

   Författare :Zsolt Jenei; Reinhold Schuch; William Evans; Stefan Klotz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular solid; high pressure; vanadium; phase transition; Physics; Fysik; Physics Of Matter; materiefysik;

   Sammanfattning : Understanding high pressure effects on simple molecular system is of great interest for condensed matter science and geophysics. Accessing the static pressure and temperature regions found in planetary interiors is made possible by the development of the Diamond Anvil Cell technique. LÄS MER
