The efficiency of operating stirred tanks is largely dependent on the turbulence characteristics of the impeller driven flow field. In this paper, we present results of large eddy simulations on stirred tank flow at Reynolds numbers up to 104 on a 1203 computational grid. Because of its computational efficiency on parallel computer platforms, a lattice-Boltzmann discretization scheme was chosen. An adaptive force field, which is able to impose (interpolated) velocity values in any point within the computational domain, represents the action of the rotating impeller.
