摘要：
Numerical tools were developed which are able to address acoustic wave propagation in dry and saturated porous media. Lattice methods, namely the lattice Boltzmann method (LBM) and the lattice spring model (LSM), can be successfully used for this purpose. The media are discretized by elementary cubes which can be obtained by computed micro-tomography [1]. Numerical results with a good precision can be obtained even for coarse geometry discretizations. Reasonable computational resources are necessary to obtain the results. The program codes can be parallelized in order to work.with large samples.
