An arbitrary Lagrangian-Eulerian approach for the simulation of immersed moving solids with Lattice Boltzmann Method

Finally, the case of a rotating two dimensional square cylinder immersed in a Poiseuille Flow, Re=80, has been numerically investigated. The results confirm that the ALE-LBM approach is able to correctly represent the physical flow features and, in particular, the transition zone between the two grids used is smooth and continuous, a sign that the error due to the interpolation process is bounded and does not diverge in time.
