  2. 16. Complex Molecules in Star-Forming Regions

    Author : Albert Nummelin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Results from spectral-line observations of molecular gas in star-forming regions, performed with the Swedish-ESO Submillimetre Telescope (SEST), are presented. The purpose of this work has been to provide better estimates of the chemical composition as a function of the physical conditions in the sources. READ MORE

  4. 17. Corrosion of High-Temperature Alloys in Molten Salts

    Author : Esraa Hamdy Mohamedin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Thermal energy storage; Pre-oxidation; Carburisation; Molten salts; Phase transition; High-temperature corrosion; Alumina-forming alloys; Alkali transition metalates; Alkali aluminate; Chromia-forming alloys; Alumina; Concentrated solar power;

    Abstract : Concentrated solar power (CSP) is an interesting technology that involves storing solar energy in the form of heat and subsequently converting it into electricity. The third-generation (Gen3) CSP plants aim to operate at temperatures >700°C, necessitating the deployment of new heat storage materials that can withstand such high operating temperatures.

  5. 18. Modelling and simulation of simultaneous forming and quenching

    Author : Greger Bergman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The objective of this thesis is to develop and evaluate numerical methods for modelling and simulation of simultaneous forming and quenching within an integrated product development environment. Simultaneous forming and quenching, also referred to as hot-stamping, is a manufacturing process for high strength automotive components such as side impact protection beams. READ MORE

  6. 19. Improving Forming of Aerospace Composite Components through Process Modelling

    Author : Jens Sjölander; Malin Åkermo; Per Hallander; Tonny Nyman; Göran Fernlund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the aerospace industry there is a constant effort to reduce the weight of aircraft. Since weight reduction has a direct impact on fuel consumption. Reducing the fuel consumption leads to botheconomical benefits through less money spent on fuel and environmental benefits through reduced CO2 emissions. READ MORE

  7. 20. Material characterisation for analyses of titanium sheet metal forming

    Author : Eva-Lis Odenberger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : New demands and opportunities for simulation driven product development, that today's finite element (FE) technology allow for, exists in modern industry. Full applicability, in which decisions based on numerical evaluations and predictions, require accurate material parameters and of course accurate modelling of remaining features. READ MORE
