  2. 1. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth

    Author : Anders Eliasson; Hasse Fredriksson; Thomas Gomez-Acebo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid phase sintering; heavy metal; particle composites; tungsten; penetration; agglomerate separation; particle interaction; parabolic flight; sounding rockets; microgravity; Kirkendall effect; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). READ MORE

  4. 2. Disintegration of Lime Mud Particles during the Causticizing Operation

    Author : Pia Tiljander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CaCO3; Ca OH 2; CaO; lime mud; mixing; particles; slaking; causticizing; disintegration; impeller;

    Abstract : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. READ MORE

  5. 3. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

    Author : Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
    Keywords : Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

    Abstract : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. READ MORE

  6. 4. Transitional and turbulent fibre suspension flows

    Author : Mathias Kvick; Fredrik Lundell; Daniel Söderberg; Lisa Prahl Wittberg; Björn Hof; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; fibre suspension; turbulence; laminar-turbulent transition; image analysis; hydrodynamic stability; cellulose nanofibrils.; Engineering Mechanics; Teknisk mekanik;

    Abstract : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. READ MORE

  7. 5. On the Agglomeration of Particles in Exhaust Gases

    Author : Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

    Abstract : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. READ MORE
