dc.description.abstractLattice Boltzmann is a numerical method for the simulation of different physical phenomena, such as incompressible flow -- Despite the fact of being a kinetic method, and therefore of unsteady nature, allows to obtain the solution of steady problems with good accuracy and efficiency -- However, the arising of pressure oscillations during the solution process and the reflective character of some of its boundary conditions have resulted in an active research interest on open boundaries, and outlet conditions in particular -- Fluid structure interaction problems are mostly of unsteady type, so the elimination of spurious pressure oscillations is desirable or even necessary -- The aim of the present work is to show, in the first place, that oscillations occur even without involving solid obstacles in the simulations, although measures to avoid them are taken, like diffusive scaling -- On the other hand, that oscillation-free results are possible to be obtained using the most basic formulation of the method, LBGK, and even conventional reflective conditions, but sacrificing the most widely used tool of the LBM method: the bounce back conditionspa
