Grid-generated turbulence was examined numerically via direct numerical simulations employing the lattice Boltzmann BGK method. A 3D flow solver developed at LSTM Erlangen, written in Fortran and optimized for vector-parallel supercomputers and commodity clusters, was employed for the predictions. The computations presented in this work were carried out partly at the High Performance Computing Center in Stuttgart (HLRS) and partly at the Leibniz Rechenzentrum in Munich (HLRB). The main scientific motivations for this work were to address the lateral inhomogeneity of turbulent quantities in grid turbulence, the decay laws of the turbulent kinetic energy, the decay laws of the turbulent dissipation rate and the Reynolds stress and dissipation...
