Kinetic closure of turbulence: collision-side modeling beyond the filtered Boltzmann equation
Francesco Marson, Orestis Malaspinas
This article extends a recently introduced kinetic closure of turbulence by developing its theoretical framework, operational realizations, and validation. In contrast with filtere…
Kinetic closure of turbulence
Francesco Marson, Orestis Malaspinas
This letter presents a kinetic closure of the filtered Boltzmann--BGK equation, paving the way toward an alternative description of turbulence. The closure retains the turbulent su…
Hermite regularization of the Lattice Boltzmann Method for open source computational aeroacoustics
Federico Brogi, Orestis Malaspinas, Bastien Chopard +1
The lattice Boltzmann method (LBM) is emerging as a powerful engineering tool for aeroacoustic computations. However, the LBM has been shown to present accuracy and stability issue…
Regularized characteristic boundary conditions for the Lattice-Boltzmann methods at high Reynolds number flows
Gauthier Wissocq, Nicolas Gourdain, Orestis Malaspinas +1
This paper reports the investigations done to adapt the Characteristic Boundary Conditions (CBC) to the Lattice-Boltzmann formalism for high Reynolds number applications. Three CBC…
Local mesh refinement sensor for the lattice Boltzmann method
Yann Thorimbert, Daniel Lagrava, Orestis Malaspinas +5
A novel mesh refinement sensor is proposed for lattice Boltzmann methods (LBMs) applicable to either static or dynamic mesh refinement algorithms. The sensor exploits the kinetic n…
Increasing stability and accuracy of the lattice Boltzmann scheme: recursivity and regularization
Orestis Malaspinas
In the present paper a lattice Boltzmann scheme is presented which exhibits an increased stability and accuracy with respect to standard single- or multi-relaxation-time (MRT) appr…
