  2. 1. Analytical vortex solutions to Navier-Stokes equation

    Author : Henrik Tryggeson; Mats Lyberg; Maarten Brons; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conical vortex; Navier-Stokes equation; analytical solution; 2-D vortices; turbulence; vortex ring; stretched vortex; coherent structures; Fluid mechanics; Strömningsmekanik;

    Abstract : Fluid dynamics considers the physics of liquids and gases. This is a branch of classical physics and is totally based on Newton's laws of motion. Nevertheless, the equation of fluid motion, Navier-Stokes equation, becomes very complicated to solve even for very simple configurations. READ MORE

  5. 3. Some Mathematical Aspects of Thermo and Fluid Dynamics

    Author : Carl Fredrik Stein; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; swirling jets; vortex breakdown; conical self-similarity; Long s jet; Taylor s hypothesis; frozen turbulence hypothesis; advection velocity; conjugate heat transfer; asymptotic analysis; swirling jets;

    Abstract : This thesis contains mathematical treatments of three issues in thermo and fluid dynamics: swirling jets and vortex breakdown, Taylor's hypothesis and conjugate heat transfer. The work on swirling jets is focused on the study of the well-posedness of the conically self-similar free-vortex solutions to the Navier--Stokes equations. READ MORE

  6. 4. Large Eddy Simulation of Turbulent Premixed and Partially Premixed Combustion

    Author : Eric Baudoin; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, a computational fluid dynamics (CFD) approach is used to study turbulent premixed and partially premixed combustion. The CFD approach is based on large eddy simulation (LES) in which the large-scale structures of the flow are resolved on a grid, leaving only the small-scale structures (subgrid scales) to be modeled.

  7. 5. Non-local behaviour from local interactions

    Author : Thomas Kvorning; Thors Hans Hansson; Ady Stern; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. READ MORE
