  2. 6. Mathematical and Physical Simulations of BOF Converters

    Author : Xiaobin Zhou; Mikael Ersson; Pär Jönsson; Hans-Jürgen Odenthal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; physical model; mathematical model; mixing time; kinetic enregy; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The purpose of this study is to develop mathematical models to explore the mixing and its related phenomena in converter bath. Specifically, first, a mathematical model of a physical model converter, which was scaled down to 1/6th of a 30 t vessel, was developed in this study. READ MORE

  6. 9. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes

    Author : Andreas Nyman; Göran Lindbergh; Mårten Behm; Signe Kjelstrup; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium‐ion batteries; Electrolytes; Transport properties; Conductivity; Diffusion coefficients; Transport number; Maxwell-Stefan equation; Simulations; Mathematical analysis; Polarization; Hybrid electric vehicles; Litiumjonbatterier; Aprotiska elektrolyter; Transport egenskaper; Konduktivitet; Diffusion koefficienter; Transporttal; Maxwell-Stefans ekvation; Simuleringar; Matematisk analys; Polarisation; Elhybridfordon; Electrochemistry; Elektrokemi;

    Abstract : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. READ MORE

  7. 10. Analysis of Dynamics of the Tippe Top

    Author : Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Tippe Top is a toy that has the form of a truncated sphere with a small peg. When spun on its spherical part on a flat supporting surface it will start to turn upside down to spin on its peg. READ MORE
