We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved
stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a threedimensional
lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number Re = 5 × 104
for this setup. Excellent agreement with energy balance equations, computational and experimental results are
shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of
turbulent production.

High-order regularization in lattice-Boltzmann equations
Mattila, Keijo; Philippi, Paulo C.; Hegele, Luiz A. (American Institute of Physics, 2017)A lattice-Boltzmann equation (LBE) is the discrete counterpart of a continuous kinetic model. It can be derived using a Hermite polynomial expansion for the velocity distribution function. Since LBEs are characterized ... -
Investigation of an entropic stabilizer for the lattice-Boltzmann method
Mattila, Keijo; Hegele, Luiz A.; Philippi, Paulo C. (American Physical Society, 2015)The lattice-Boltzmann (LB) method is commonly used for the simulation of fluid flows at the hydrodynamic level of description. Due to its kinetic theory origins, the standard LB schemes carry more degrees of freedom than ...
