Abstract

We have developed a finite volume based dynamically adaptive Lattice Boltzmann method for large eddy simulation of weakly compressible flows in moving complex geometry. The scheme is implemented as a patch solver within the massively parallel block-structured AMR framework AMROC. We will report on details of the method and first scalability results on several hundreds cores. Technically relevant three-dimensional simulations of wind turbines with interacting flow fields will demonstrate the benefit of the overall approach.
