  4. 3. Investigation of Outflow Boundary Conditions for Convection-Dominated Incompressible Fluid Flows in a Spectral Element Framework

    University essay from KTH/Numerisk analys, NA

    Author : Erik Boström; [2015]
    Keywords : ;

    Abstract : In this thesis we implement and study the effects of different convective outflow boundary conditions for the high order spectral element solver Nek5000 in the context of solving convective-dominated fluid flow problems. By numerical testing we show that the convective boundary conditions preserve the spatial and temporal convergence rates of the solver. READ MORE
