Title: Implementation of a multiphase Lattice Boltzmann Method for the simulation of water retention behaviour of CT scanned granular media
Language: English
Authors: Milatz, Marius  
Keywords: Unsaturated granular soils; Water retention behaviour; Multiphase Lattice Boltzmann Method (LBM)
Issue Date: 7-Jun-2022
Abstract (english): 
This data set contains a multiphase Lattice Boltzmann implementation (C++ code) for the simulation of water retention behaviour in granular media and related example files to run a simulation of cyclic drainage and imbibition in a cubic computational domain that is derived from binarised CT data including spatial information of the solid and pore distribution.
