Analysis of fourth-order accurate symmetry-preserving boundary conditions for the incompressible Navier-Stokes equations
conference paper
In this paper we investigate symmetry-preserving boundary conditions for a fourth-order symmetry-preserving finite volume method, to able to do accurate turbulence simulations for wind-turbine wake applications. It is found that the use of Dirichlet conditions limits the fourth-order method to (at most) second order. However, on properly chosen non-uniform grids, fourth-order behavior can be displayed on coarse grids, which can make the method attractive for simulations of turbulent flow.
