Physics-informed convolutional neural networks for fluid flow through porous media
RafaÅ Topolnicki, PaweÅ DÅotko, Maciej Matyka
Accurate simulation of fluid flow in porous media is challenging due to complex pore-space geometries and the computational cost of solving the Navier-Stokes equations. This diffic…
The role of porosity in the transition to inertial regime in porous media flows
Dawid Strzelczyk, Gregor Kosec, Maciej Matyka
In this work, we investigate the fundamental physical mechanism of the transition from Darcy to inertial (Darcy-Forchheimer) regime in steady-state flows through porous media, with…
Cross-validation of meshless Navier-Stokes solvers in porous media flows
Dawid Strzelczyk, Miha Rot, Gregor Kosec +1
In this paper, two mesh-free CFD solvers for pore-scale fluid flow through porous media are considered, namely the Lattice Boltzmann Method with the two relaxation time collision t…
Inertial effects on fluid flow through low-porosity media
Sahrish Batool Naqvi, Damian Ånieżek, Dawid Strzelczyk +2
We investigated the nonlinear effects of gravity-driven fluid flow through a two-dimensional, low-porosity, packed bed of stubby stone grains. We focused on preferential channel fo…
Modeling inertial flows with meshless Lattice Boltzmann Method
Dawid Strzelczyk, Maciej Matyka
One of the limitations of the Lattice Boltzmann Method in simulating inertial flows is the coupling of the discretization of space to the velocity discretization. It requires an in…
