1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

3. Subgrid finite volume preconditioner for Discontinuous Galerkin implemented in the DUNE framework
University essay from Lunds universitet/Matematik LTHAbstract : A Jacobian free multigrid preconditioner for linear problems arising from Implicit Discontinuous Galerkin (DG) discretizations is implemented. The preconditioner is based on a multigrid method for a low order Finite volume (FV) discretization on a subcellgrid. L2-projections are introduced as a strategy to translate between the discretizations. READ MORE

4. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions
University essay from Mälardalens högskola/Framtidens energiAbstract : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. READ MORE

5. Modelling of water and material transport in River Storån to Lake Bolmen
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. READ MORE
