Abstract

Simulation results based on the lattice Boltzmann method are shown for the turbulent lid-driven twodimensional cavity flow at Reynolds number 100,000. We make use of a boundary condition scheme that significantly improves stability for simulation of turbulent flows within the lattice Boltzmann method framework. Explicit expressions for the turbulent kinetic energy budget are presented and its evolution is studied in 2D turbulence. We also look at the evolution of enstrophy and palinstrophy.
