| 1 | Lattice Boltzmann Analysis of Fluid-Structure Interaction with Moving Boundaries显示文摘This work is concerned with the modelling of the interaction of fluid flow with flexibly supported rigid bodies.The fluid flow is modelled by Lattice-Boltzmann Method,coupled to a set of ordinary differential equations describing the dynamics of the solid body in terms its elastic and damping properties.The time discretization of the body dynamics is performed via the Time Discontinuous Galerkin Method.Several numerical examples are presented and highlight the robustness and efficiency of the proposed methodology,by means of comparisons with previously published results.The examples show that the present fluid-structure method is able to capture vortexinduced oscillations of flexibly-supported rigid body. | Alessandro De Rosis Giacomo Falcucci Stefano Ubertini Francesco Ubertini Sauro Succi | 2013 | Communications in Computational Physics2013，13，3： | 1 |

| 4 | Lattice Boltzmann Methods for Multiphase Flow Simulations across Scales显示文摘The simulation of multiphase flows is an outstanding challenge,due to the inherent complexity of the underlying physical phenomena and to the fact that multiphase flows are very diverse in nature,and so are the laws governing their dynamics.In the last two decades,a new class of mesoscopic methods,based on minimal lattice formulation of Boltzmann kinetic equation,has gained significant interest as an efficient alternative to continuum methods based on the discretisation of the NS equations for non ideal fluids.In this paper,three different multiphase models based on the lattice Boltzmann method(LBM)are discussed,in order to assess the capability of the method to deal with multiphase flows on a wide spectrum of operating conditions and multiphase phenomena.In particular,the range of application of each method is highlighted and its effectiveness is qualitatively assessed through comparison with numerical and experimental literature data. | Giacomo Falcucci Stefano Ubertini Chiara Biscarini Silvia Di Francesco Daniele Chiappini Silvia Palpacelli Alessandro De Maio Sauro Succi | 2011 | Communications in Computational Physics2011，9，2： | 0 |
