Abstract
"The Lattice Boltzmann Method (LBM) is a powerful technique. introduced in Computational Fluid Dynamics (CFD) a couple of. decades ago. Since then, many important results have been obtained in. the most different fields of CFD. The main advantages of the LBM. with respect to other numerical method are its versatility and intrinsic. linearity. The aim of this work is to present the formulation and the. application of the LBM to two-layered 2D shallow water flows. interacting with obstacles. LBM numerical results obtained in this work. are validated by means of comparisons with experimental and. numerical results published in literature and relative to known and well. defined benchmark cases. Then LBM numerical results, concerned with. the interaction of the gravity current with obstacles, are presented. They. show the ability of the proposed method to reproduce the essential. features of the considered phenomenon."I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
