High Performance Simulation of Fluid Flow in Complex Porous Media using LBM

To study the detailed fluid flow in porous media with complex microstructure geometries, a Fluid Flow Simulator for Complex Microscale Porous Media (FPM) is being developed as a template solver for users to simulate the fluid flow in complex geometry and further reveal the properties of various porous media with the complex microstructure. FPM will be designed all-purpose to install on various supercomputers for larger-scale parallel simulations. Based on Lattice Boltzmann method (LBM), FPM has four master features: 1) Stochastic Geometry Generator (SGG), with which to imitate any kind of porous media geometries and explore new materials. 2) Raw in-Data Preprocessor (RDP), to deal with real geometry data derived from plenty of porous media, which are dedicated to simulate the complex porosities. 3) Dynamics Physics Modeling (DPM), including more complicated dynamic models as a core, especially the complex boundary conditions and multi-physics coupling, will be further considered to implement precise simulation. 4) Data Visualization (DV), to post process the output data. FPM will deeply figure out the relationship between micro geometries and macro phenomena, the usage of which will be not only restricted for microscale simulation of porous media, but also useful for evaluating the material properties (i.e. permeability) in any complicated but with similar macroscale structures.
