  1. 1. Investigations of thermophysical properties of slags with focus on slag-metal interface

    Författare :Luckman Muhmood; Seshadri Seetharaman; Nurni Neelakandan Viswanathan; Allan Cramb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. LÄS MER

  3. 2. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

    Författare :Akira Yamauchi; KTH; []
    Nyckelord :Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

    Sammanfattning : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. LÄS MER

  4. 3. Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions

    Författare :Sam Fredriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Air.sea gas exchange; Turbulence; Heat flux; Natural convection; Shear; Direct numerical simulations; Gas transfer velocity; IR; Flux-chambers;

    Sammanfattning : The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. LÄS MER

  5. 4. Tailoring the self-assembly, interfacial properties and rheological behaviour of sugar-based surfactants

    Författare :Johan Larsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sugar-based surfactants; Self-assembly; Scattering; Rheology; Adsorption; Sustainable materials;

    Sammanfattning : Surfactants are important ingredients in many formulated products used in everyday life. Many of these surfactants originates from fossil-based materials and degrades slowly in aquatic systems. LÄS MER

  7. 5. Characterisation of water-based floxographic inks and their interacitons with polymer-coated board

    Författare :Maria Rentzhog; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : This licentiate thesis comprises two parallel studies dealing with water-based flexographic inks on PE-coated liquid packaging board. The commercial waterbased inks that were used in both studies vary in type of pigment and acrylatepolymer vehicle, and in pigment/vehicle mixing proportions. LÄS MER
