Large-eddy simulation of turbulent open-channel flow over three- dimensional dunes

A large-eddy simulation study has been undertaken to investigate the turbulent structure of openchannel flow over three-dimensional (3D) dunes. The governing equations have been discretised using the finite volume method, with the partial cell treatment being implemented in a Cartesian grid form to deal with the 3D dune topography. The numerical model predicted free surface elevations, mean flo...

Numerical Analysis of Three-dimensional Turbulent Flow by Finite Element Method and Large Eddy Simulation

Formulation, implementation and applications of a numerical algorithm to simulate turbulent, incompressible, isothermal flows are the main objectives of this work. The transient three-dimensional flow is analyzed using an explicit Taylor-Galerkin scheme and the finite element method with hexahedrical eight-node element. The scheme adopted for turbulence treatment is Large Eddy Simulation. For s...

Large-eddy simulation and wall modelling of turbulent channel flow

We report large-eddy simulation (LES) of turbulent channel flow. This LES neither resolves nor partially resolves the near-wall region. Instead, we develop a special near-wall subgrid-scale (SGS) model based on wall-parallel filtering and wall-normal averaging of the streamwise momentum equation, with an assumption of local inner scaling used to reduce the unsteady term. This gives an ordinary ...
