Grid Refinement for Lattice-BGK Models
Olga Filippova,Dieter Hänel +1 more
TL;DR: A local second-order grid refinement scheme for the lattice?BGK model is proposed and a boundary-fitting scheme for complicated geometries are applied to simulate a benchmark problem of flow past a cylinder in a channel with small and moderate Reynolds numbers.
Journal ArticleDOI
A Novel Lattice BGK Approach for Low Mach Number Combustion
Olga Filippova,Dieter Hänel +1 more
TL;DR: An extended lattice Boltzmann (BGK) model is presented for the simulation of low Mach number flows with significant density changes and with a boundary fitting formulation and local grid refinement the scheme enables accurate and efficient computations of lowMach number reactive flows in complex geometry on the simplest Cartesian grids.
Journal ArticleDOI
Multiscale lattice Boltzmann schemes with turbulence modeling
TL;DR: In this article, the viability of multiscale lattice Boltzmann schemes for numerical simulation of turbulent flows is discussed and numerically demonstrated for turboaxial machine applications, and the extension of boundary-fitting formulas based on wall functions is proposed, which enables the efficient computation of turbulent flow in complex curvilinear geometry using a simple Cartesian grid.
Journal ArticleDOI
Applying the lattice Boltzmann equation to multiscale fluid problems
TL;DR: In this paper, the theory and application of the lattice Boltzmann equation to multiscale physics in fluids is discussed and two examples relevant to real-life applications are presented: airflow around an airfoil and reactive flow in micropores.
Journal ArticleDOI
Acceleration of Lattice-BGK schemes with grid refinement
Olga Filippova,Dieter Hänel +1 more
TL;DR: Further improvement of the LBGK method with local grid refinement is proposed, enabling the use of smaller amount of time steps on refined grids without impairing the spatial or temporal accuracy.
