  2. 1. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

    Author : Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; Thermal energy engineering; Termisk energiteknik;

    Abstract : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. READ MORE

  4. 2. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Author : Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glacier-ocean interactions; Arctic; Calving; naturgeografi; Physical Geography;

    Abstract : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. READ MORE

  5. 3. Mechanical Behaviour of Adhesive Joints in Cartonboard for Packaging

    Author : Christer Korin; Magnus Lestelius; Nils Hallbäck; Christophe Barbier; Christer Fellers; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot melt Adhesives; Carton board; Y-peel; Peel strength; Chemical Engineering; Kemiteknik;

    Abstract : A cartonboard package is often sealed and closed with an adhesive – either a hot-melt adhesive (adhesives that are applied in a molten state on the cartonboard) or a dispersion adhesive (adhesives that are applied as water-based dispersions). This thesis focuses on the process of hot-melt gluing, and how material properties and process conditions affect the performance of the adhesive joint. READ MORE

  6. 4. Phenomenological and mechanistic modeling of melt-structure-water interactions in a light water reactor (LWR) severe accident

    Author : Anh Bui Viet; KTH; []
    Keywords : ;

    Abstract : Severe accidents in light water reactors have been the fotalpoint of much research, performed in the last two decades,aimed at understarrding the inherent physical phenomena and toevaluate proposed accident management schemes for mitigatingthe consequences of such accidents. Severe accident progressionand consequences, av the reactor core overheats and melts, areintimately related to the interactions of the melt with coolant(water) and structures. READ MORE

  7. 5. On the effect of nitrogen, hydrogen and cooling rate on the solidification and pore formation in Fe-base and Al-base alloys

    Author : Advenit Makaya; Hasse Fredriksson; Zhongyun Fan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Porous metals; Metal foams; Gas solubility; Fe-base alloys; Al-base alloys; M7C3 carbides; Al3Ti; Al3Fe; Rapid solidification; Metastable phases; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : Experiments on the production of porous metallic materials were performed on Fe-base and Al-base alloys. The method involves dissolution of gases in the liquid state and solidification at various cooling rates. The alloy compositions were selected to induce solidification of primary particles intended to control the pore distribution. READ MORE
