A large eddy lattice Boltzmann simulation of magnetohydrodynamic turbulence

Large eddy simulations (LES) of a lattice Boltzmann magnetohydrodynamic (LB-MHD) model are performed for the unstable magnetized Kelvin-Helmholtz jet instability. This algorithm is an extension of Ansumali et al. [1] to MHD in which one performs first an expansion in the filter width on the kinetic equations followed by the usual low Knudsen number expansion. These two perturbation operations d...

Inertial consistent subgrid model for large-eddy simulation based on the lattice Boltzmann method

The recently introduced inertial-range IR consistent Smagorinsky model and the classical Smagorinsky model are applied to the large-eddy simulation LES of decaying homogeneous isotropic turbulence based on the lattice Boltzmann method LBM , which is implemented using the 19-velocity D3Q19 lattice model. The objectives of this study are to examine the effectiveness of the LES-LBM technique for s...

Wall model for large-eddy simulation based on the lattice Boltzmann method

An original wall-model for lattice Boltzmann based large-eddy simulation is presented. It relies on either an analytical profile for the velocity profile within the first off-wall cell or the solution of Turbulent Boundary Layer Equations. The latter are solved thanks to a meshless approach to obtain a user-friendly method. The proposed method is observed to be both robust and accurate, yieldin...

Implicit Large Eddy Simulation of Flow in a Micro-Orifice with the Cumulant Lattice Boltzmann Method

Abstract: A detailed numerical study of turbulent flow through a micro-orifice is presented in this work. The flow becomes turbulent due to the orifice at the considered Reynolds numbers (∼104). The obtained flow rates are in good agreement with the experimental measurements. The discharge coefficient and the pressure loss are presented for two input pressures. The laminar stress and the genera...

Direct Building Energy Simulation Based on Large Eddy Techniques and Lattice Boltzmann Methods

The modeling of convective flows with 3D lattice Boltzmann fluid dynamics is presented using a lattice BGK approach for low Mach number flows with variable density combined with a large eddy turbulence model. The ability to resolve non− Boussinesq density varying problems is depicted for two dimensional Rayleigh−Bénard−convection at a Rayleigh number Ra = 800,000. A complex three−dimensional ex...
