Investigations of Three- Dimensional Turbulent Cavity Flow Using Large Eddy Simulation Approach

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 ...

Large-eddy Simulation of a Particle- Laden Turbulent Channel Flow

Large-eddy simulations of a vertical turbulent channel flow with 420,000 solid particles are performed in order to get insight into fundamental aspects of a riser flow. The question is addressed whether collisions between particles are important for the flow statistics. The turbulent channel flow corresponds to a particle volume fraction of 0.013 and a mass load ratio of 18, values that are rel...
