  2. 1. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Author : Gregory Makusa; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  4. 2. Impact of Metallic Projectiles on a Ceramic Target Surface : Transition Between Interface Defeat and Penetration

    Author : René Renström; Bengt Lundberg; Patrik Lundberg; Nils-Gunnar Ohlson; Uppsala universitet; []
    Keywords : Engineering physics; Projectile; Cylindrical; Conical; Yield strength; Compressibility; Perfect flow; Self-similar flow; Interface defeat; Dwell; Teknisk fysik; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Abstract : The purpose of this thesis is to gain understanding of the load on flat target surfaces produced by projectile impact. Models are proposed from which upper and lower bounds can be derived for the transition be-tween interface defeat and normal penetration. READ MORE

  5. 3. On the Modelling of Mechanical Dewatering in Papermaking

    Author : Vinicius Lobosco; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; paper; modelling; dewatering; forming; wet pressing; fibre network stress; rheology; hysteresis; intra-fibre water; compressibility; structural stress; stress-strain; restricted gels; swelling;

    Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

  6. 4. Phase-changing flows: numerical methods and fully resolved simulations

    Author : Nicolo Scapin; Luca Brandt; Christophe Duwig; Outi Tammisola; Matthias Ihme; KTH; []
    Keywords : Phase change; interface-resolved simulations; compressibility; evaporating droplets; evaporation-driven thermal convection.; Teknisk mekanik; Engineering Mechanics;

    Abstract : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.

  7. 5. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

    Author : Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

    Abstract : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. READ MORE
