  1. 1. Study on some phenomena of slag in steelmaking process

    Författare :Liushun Wu; Sichen Du; Carlo Mapelli; KTH; []
    Nyckelord :Slag viscosity; calcium fluoride; fluid viscosity with particles; mixture viscosity; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. LÄS MER

  3. 2. The influence of inertia on the rotational dynamics of spheroidal particles suspended in shear flow

    Författare :Tomas Rosén; Fredrik Lundell; Minh Do-Quang; Johan Revstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-spherical particles; non-linear dynamics; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Dispersed particle flows occur in many industrial, biological and geophysical applications. The knowledge of how these flow behave can for example lead to improved material processes, better predictions of vascular diseases or more accurate climate models. LÄS MER

  4. 3. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

    Författare :Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

    Sammanfattning : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. LÄS MER

  5. 4. Investigation of Thermal Performance of Cylindrical Heatpipes Operated with Nanofluids

    Författare :Morteza Ghanbarpourgeravi; Rahmatollah Khodabandeh; Björn Palm; Oronzio Manca; KTH; []
    Nyckelord :Nanofluid; heat pipe; thermal resistance; heat transfer coefficient; evaporator; condenser; wick; porous layer; heat flux; inclination angle; thermal conductivity; viscosity; Energiteknik; Energy Technology;

    Sammanfattning : Nanofluids as an innovative class of heat transfer fluids created by dispersing nanometre-sizedmetallic or non-metallic particles in conventional heat transfer fluids displayed the potential toimprove the thermophysical properties of the heat transfer fluids. The main purpose of this study is toinvestigate the influence of the use of nanofluids on two-phase heat transfer, particularly on thethermal performance of the heat pipes. LÄS MER

  7. 5. Simulation of deformable objects transported in fluid flow

    Författare :Arash Alizad Banaei; Luca Brandt; Markus Holzner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.
