Journal ArticleDOI
Multiscale simulation of turbulent flow interacting with porous media based on a massively parallel implementation of the cumulant lattice Boltzmann method
TL;DR: In this paper, the aerodynamic effects of porous segments of the surface by numerical methods for aerodynamic design of wings, taking into account porosity and roughness as a function of Reynolds number, are modeled using the cumulant lattice Boltzmann method.
Journal ArticleDOI
Under-resolved and large eddy simulations of a decaying Taylor–Green vortex with the cumulant lattice Boltzmann method
TL;DR: In this paper, a comprehensive analysis of the cumulant lattice Boltzmann model with the three-dimensional Taylor-Green vortex benchmark at Reynolds number 1600 was presented, and the results showed that the Cumulant model with fourth-order convergent diffusion showed much better results than single relaxation time methods.
Journal ArticleDOI
Effect of porous material on trailing edge sound sources of a lifting airfoil by zonal Overset-LES
TL;DR: In this article, the effects of porous material on the trailing edge of a 3D cambered airfoil were modeled by a volume averaged approach with a linear Darcy term and a non-linear Forchheimer term.
Journal ArticleDOI
Cumulant lattice Boltzmann simulations of turbulent flow above rough surfaces
TL;DR: Comparisons with a reference finite difference-based simulator and with the datasets from wind-tunnel experiments indicate good agreement and suitability of the lattice Boltzmann method for these types of problems.

Massively Parallel Lattice Boltzmann Simulations of Turbulent Flow over and Inside Porous Media
TL;DR: DNS/LES simulations of turbulent flow over a DLR-F16 wing profile at a Reynolds number of \(10^6\) using a cumulant lattice Boltzmann method, implemented in the object-oriented framework VirtualFluids is reported.
