High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
Abstract
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.
