Wave Propagation in Heterogeneous Media with Cavities by an LSM/LBM-Coupled Model
https://orcid.org/0000-0001-9952-9294
Abstract Lattice methods, namely the lattice Boltzmann method and the lattice spring model, can be successfully used to address acoustic wave propagation in dry and saturated porous media. The resulting code can upscale porous media properties or study direct time simulations in complex media. Only the second application is detailed here for various flat media which contain or not a cavity, which possess uniform properties or not; an explosion is simulated and the accelerations are measured at the surface. The data show that when the medium is simple, the cavity can be easily located, which is not true when it is heterogeneous.
