چکیده
Abstract. 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.

A Fast Immersed Boundary Fourier Pseudo-spectral Method for Simulation of the Incompressible Flows
Abstract The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...
متن کاملA High Order Accurate MultiGrid Pressure Correction Algorithm for Incompressible Navier-Stokes Equations
A fourth-order accurate finite-difference compact numerical scheme coupled with a geometric MultiGrid technique is introduced for an efficient incompressible NavierStokes solver on staggered meshes. Incompressibility condition is enforced iteratively by solving a Poisson-type equation performing global pressure correction. Its application is the most computationally demanding part of the algori...
متن کاملEnergy Stable Boundary Conditions for the Nonlinear Incompressible Navier-Stokes Equations
The nonlinear incompressible Navier-Stokes equations with boundary conditions at far fields and solid walls is considered. Two different formulations of boundary conditions are derived using the energy method. Both formulations are implemented in both strong and weak form and lead to an estimate of the velocity field. Equipped with energy bounding boundary conditions, the problem is approximate...
متن کاملAccuracy analysis of explicit Runge-Kutta methods applied to the incompressible Navier-Stokes equations
This paper investigates the temporal accuracy of the velocity and pressure when explicit Runge–Kutta methods are applied to the incompressible Navier–Stokes equations. It is shown that, at least up to and including fourth order, the velocity attains the classical order of accuracy without further constraints. However, in case of a time-dependent gradient operator, which can appear in case of ti...
متن کاملDns of Turbulent Flow and Heat Transfer in a Channel with Surface Mounted Cubes
The turbulent flow and heat transfer in a channel with surface mounted cubical obstacles forms a generic example of a problem that occurs in many engineering applications, for instance in the design of cooling devices. We have performed a numerical simulation of it without using any turbulence models. This approach is the most accurate but also the most expensive way of computing complex turbul...
