    Författare :Vedad Tojaga; Sören Östlund; Artem Kulachenko; T. Christian Gasser; Emanuela Bosco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Staggered; Monolithic; Fracture; Constitutive modeling; Strong discontinuity approach SDA ; Simo-Reissner beam theory; Geometrically exact beam theory; Minimeringsalgoritm; Simo-Reissner balkteori; Icke kompatibla deformationsmode; Konstitutiva model; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This thesis summarizes seven appended papers dealing with: (1) The fracture of fibrous materials, e.g. LÄS MER

  3. 2. Initial-Boundary-Value Problems for the Stokes and Navier–Stokes Equations on Staggered Grids

    Författare :Jonas Nilsson; Bertil Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stokes equations; Navier-Stokes equations; boundary conditions; staggered grids; higher-order methods; Numerical Analysis; Numerisk analys;

    Sammanfattning : In the first part of the thesis various types of boundary conditions for the steady state Stokes equations are considered. We formulate the boundary conditions in a new way, such that the boundary value problem becomes non-singular, and derive estimates of the solution. LÄS MER

  4. 3. Foam modeling including pore gas interaction for crashworthiness analysis

    Sammanfattning : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. LÄS MER

  5. 4. Investigations of Heat Transfer and Fluid Flow in the Pocket Region of a Gas Turbine Engine and Cooling of a Turbine Blade

    Författare :Jian Liu; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pocket cavity; symmetric vane; Liquid Crystal Thermography; truncated ribs; staggered arrangement; perforated ribs; secondary flows; endwall film cooling; leading edge; turbine vane; coolant coverage;

    Sammanfattning : In the present work, heat transfer within gas turbine applications are investigated bothexperimentally and numerically. The main content concerns heat transfer and fluidflow over the pocket region and cooling of a turbine blade. LÄS MER

  7. 5. A high order method for simulation of fluid flow in complex geometries

    Författare :Erik Stålberg; KTH; []
    Nyckelord :Technology; Navier-Stokes equations; compact high order difference methods; approximate factorization; curivilinear staggered grids; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A numerical high order difference method is developed for solution of the incompressible Navier-Stokes equations. The solution is determined on a staggered curvilinear grid in two dimensions and by a Fourier expansion in the third dimension. LÄS MER
