  1. 11. Hybrid Grid Generation for Viscous Flow Computations Around Complex Geometries

    Författare :Lars Tysell; Laszlo Fuchs; Nigel P. Weatherill; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; grid generation; unstructured grids; hybrid grids; surface grids; three-dimensional grids; adaptive grids; moving grids; grid quality; accuracy; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : A set of algorithms building a program package for the generation of twoandthree-dimensional unstructured/hybrid grids around complex geometrieshas been developed. The unstructured part of the grid generator is based on the advancing frontalgorithm. LÄS MER

  3. 12. Cosmological models, nonideal fluids and viscous forces in general relativity

    Författare :Daniele Gregoris; Kjell Rosquist; Alan Coley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gravity; exact model; black hole; friction; teoretisk fysik; Theoretical Physics;

    Sammanfattning : This thesis addresses the open questions of providing a cosmological model describing an accelerated expanding Universe without violating the energy conditions or a model that contributes to the physical interpretation of the dark energy. The former case is analyzed considering a closed model based on a regular lattice of black holes using the Einstein equation in vacuum. LÄS MER

  7. 15. The self-spreading double bilayer/Advances in lipid membrane nanotechnology

    Författare :Irep Gözen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; pore; lipid double bilayer; rupture; crackling noise; tension; self-spreading; vesicle; flat giant unilamellar vesicle; viscous fingering.;

    Sammanfattning : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. LÄS MER
