Abstract
Porous materials can be found in numerous areas of life (e. g., applied science, material science), however, the simulation of the fluid flow and transport phenomena through porous media is a significant challenge nowadays. Numerical simulations can help to analyze and understand physical processes and different phenomena in the porous structure, as well as to determine certain parameters that are difficult or impossible to measure directly or can only be determined by expensive and time-consuming experiments. The basic condition for the numerical simulations is the 3D geometric model of the porous material sample, which is the input parameter of the simulation. For this reason, geometry reconstruction is highly critical for pore-scale analysis. This paper introduces a complex process for the preparation of the microstructure's geometry in connection with a coupled FEM-CFD two-way fluid-structure interaction simulation. Micro-CT has been successfully applied to reconstruct both the fluid and solid phases of the used porous material.
Highlights
Fluid flows are mostly analyzed above atomic-scale by engineers and researchers, in the industry, a pore-scale specification is commonly required, which is described by the equation found on Darcy's Law, together with the transport of mass by the advection-dispersion equation, in which bulk averaged fluxes satisfy the two equations [1,2,3,4,5]

Summary
Fluid flows are mostly analyzed above atomic-scale by engineers and researchers, in the industry, a pore-scale specification is commonly required, which is described by the equation found on Darcy's Law, together with the transport of mass by the advection-dispersion equation, in which bulk averaged fluxes satisfy the two equations [1,2,3,4,5]. Due to the unique and extremely complex geometry of natural porous materials, solving the general governing equations of fluid dynamics (Navier-Stokes or Stokes) is still a challenging task. The field of fluid flow and transport of porous materials have been completely changed by the improvement of various visualization techniques (e.g., micro-CT), which allows three-dimensional imaging of samples at several resolution ranges, even by capturing the internal structure [2, 6, 9, 12,13,14,15,16,17,18,19]. The properties of the porous material are, in some ways, "smeared" over the solid body and pores, a too "coarse" description of the geometry can have a negative impact on the investigated fluid flow behavior [4]. In the present flow problem, the fluid region (Ωf ) and the porous phase (Ωp ) are sharing a common interface ( Γi ). Non-manifold vertex consists if any of its connected faces have no other link with the rest of its connected
