摘      要：We couple different flow models,i.e.a finite element solver for the Navier-Stokes equations and a Lattice Boltzmann automaton,using the framework Peano as a common *** new coupling strategy between the meso-and macroscopic solver is presented and validated in a 2D channel flow *** results are in good agreement with theory and results obtained in similar works by Latt et *** addition,the test scenarios show an improved stability of the coupledmethod compared to pure Lattice Boltzmann simulations.
