the so-called lattice-boltzmann-method is a relatively young numerical method for the computation of fluid mechanics. in contrary to 'classical' techniques of computational fluid dynamics where the navier-stokes-equations - a system of partial differential equations describing the macroscopic behavior of a flow - are discretized and solved, the lattice-boltzmann-method starts from the microscopic description of a flow, the boltzmann-equation. it is a time-explicit procedure based on a strongly simplified kinetic theory, yet it is approximating the navier-stokes equations. the presentation gives a short overview about some basic principles of the lattice-boltzmann-method. typical engineering applications, in particular the feasibility of describing aeroacoustic phenomena (i.e. sound generated by flows which typically requires a time-dependent calculation of pressure and density within a fluid), are pointed out, and a partitioned approach for the coupled simulation of flows and structures is presented.
