  2. 6. Optimization of Chemical Kinetic Mechanisms and Numerical Simulations of Industrial Gas Turbine Burners

    Author : Abdallah Abou-Taouk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAS-SST; LES; Gas Turbine Combustion; Swirling Flow; Global Mechanism; Finite Rate Chemistry; Partially Premixed Flames; Chemistry Reduction; RANS;

    Abstract : Increasing demands on environmentally friendly energy conversion indicate that pollutants need to be reduced. Computational Fluid Dynamics is efficiently used today in turbulent reaction flow simulations to gain a deeper understanding of the combustion process and consequently be able to improve combustor design and reduce emissions.

  4. 7. Protein aggregation: Computational modeling and Monte Carlo algorithm development

    Author : Sigurdur Jonsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; protein aggregation; disordered proteins; Fysicumarkivet A:2014:Jonsson;

    Abstract : Although organisms have evolved sophisticated cellular mechanisms for regulating their various protein networks, proteins sometimes start to clump together in an uncontrolled way. The aggregation of proteins has been associated with a range of serious diseases. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic vortex; nonlinear mechanics; isolated resonance; nonlinear frequency tuning; chaotic dynamics; parametric interaction; Thiele equation; Monte Carlo simulations; Ito processes; bistability; tunneling magneto-resistance; Magnetisk-virvel; icke-linjär dynamik; isolerad resonans; icke-linjär frekvens-optimering; kaotisk dynamik; parametrisk interaktion; Thiele-ekvation; Monte Carlo-simuleringar; Ito-processer; bistabilitet; tunnelmagneto-resistans.; Fysik; Physics;

    Abstract : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. READ MORE

  6. 9. Simulation of turbocharged SI-engines - with focus on the turbine

    Author : Fredrik Westin; Hans-Erik Ångström; Gordon P Blair; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering design; turbocharging simulation 1D turbine accuracy SI-engine; Konstruktionsteknik; Construction engineering; Konstruktionsteknik;

    Abstract : The aim is to share experience gained when simulating (and doing measurements on) the turbocharged SI-engine as well as describing the limits of current state of the technology. In addition an overview of current boosting systems is provided. READ MORE

  7. 10. High order difference approximations for the linearized Euler equations

    Author : Stefan Johansson; Bernhard Müller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The computers of today make it possible to do direct simulation of aeroacoustics, which is very computational demanding since a very high resolution is needed.In the present thesis we study issues of relevance for aeroacoustic simulations. Paper A considers standard high order difference methods. READ MORE
