Abstract
Abstract- A Lattice Boltzmann model is constructed for the simulation of water percolation through coffee. The model describes the dynamics of two uids (water and air) through a layer of porous medium (coffee), where the porous medium may be eroded by the ow of water. Surface tension between the uids is included, and a multi-relaxation scheme is used to improve numerical stability at low viscosities. Moreover, a probabilistic algorithm is included to model erosion, transport and deposition of coffee particles.
