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

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

    Abstract : 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. READ MORE

  6. 4. A high order method for simulation of fluid flow in complex geometries

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

    Abstract : 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. READ MORE

  7. 5. Development of Graphitic Carbon Nitride based Semiconductor Photocatalysts for Organic Pollutant Degradation

    Author : Jing Wang; Pär Jönsson; Anders Palmqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; graphitic carbon nitride; visible light-driven photocatalyst; staggered band alignment; electron-hole pair separation; band edge position; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : As a potential solution to the global energy and environmental pollution, design and synthesis of artificial photocatalysts with high activities have attracted increasing scientific interests worldwide. In recent years, the graphitic carbon nitride (g-C3N4) has shown new possible applications in the photocatalytic field due to its unique properties. READ MORE
