  2. 1. Transonic flow: large eddy simulation, numerical methods and subgrid modeling

    Author : Christian Wollblad; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; SGS modeling; Transonic flow; semi-implicit numerical scheme; shock wave turbulent boundary layer interaction;

    Abstract : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. READ MORE

  4. 2. Prediction, modeling, and refinement of protein structure

    Author : Per Larsson; Arne Elofsson; Erik Lindahl; Barry Honig; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURAL SCIENCES; Protein structure prediction; Multiple alignments; Quality assessment; Molecular dynamics; Implicit solvent; Refinement; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik; Statistical mechanics; Statistisk mekanik; Biochemistry; biokemi;

    Abstract : Accurate predictions of protein structure are important for understanding many processes in cells. The interactions that govern protein folding and structure are complex, and still far from completely understood. However, progress is being made in many areas. Here, efforts to improve the overall quality of protein structure models are described. READ MORE

  5. 3. Computational modeling of hot rolling

    Author : Jonas Edberg; Luleå tekniska universitet; []

    Abstract : This thesis consists of six papers on finite element simulations of the hot rolling of plates. Different friction and material models have been evaluated. The work includes both numerical simulation and experimental verification. READ MORE

  6. 4. Large Eddy Simulation of Impinging Jets

    Author : Thomas Hällqvist; Laszlo Fuchs; Pierre Sagaut; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impinging jet; large eddy simulation; heat transfer; vortex formation; circular jet; forcing; inflow conditions; implicit modeling.; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis deals with Large Eddy Simulation (LES) of impinging air jets. The impinging jet configuration features heated circular jets impinging onto a flat plate. The problem addressed here is of generic nature, with applications in many engineering devices, such as cooling of components in gas turbines, in cars and electronic devices. READ MORE

  7. 5. Mathematical modeling and numerical tools for simulation and design of light scattering in paper and print

    Author : Per Edström; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; mathematical modeling; radiative transfer; integro-differential equations; inverse problems; parameter estimation; solution method; numerical performance; light scattering; paper industry applications; Kubelka-Munk; MATHEMATICS; MATEMATIK;

    Abstract : This work starts with a real industrial problem - the perceived need for a moredetailed and more accurate model for light scattering in paper and print than theKubelka‐Munk model of today. A careful analysis transfers this problem into aphysical description of the phenomena involved. READ MORE
