Zur Strömungssimulation in Einzelklüften: Gegenüberstellung von numerischen Methoden und Experiment
… under study can be described by the law of FORCHHEIMER (1901). It is in accordance with the Local Cubic Law but involves an additional term that takes into account inertial effects proportional to the square of the flow velocity and the empirical Forchheimer coefficient. This flow law that …

Development of Potential Remote Coal Mine Fire Response Measures: Use of Multiple Passive Source Tracers and Simulation of High Expansion Foam Flow in Simulated Gob Material
… part of this thesis determines the Darcy and Forchheimer values for high expansion foam flow in simulated gob material with a lab experiment. The experiment was replicated in the CFD software, OpenFOAM, to validate the methods for calculation of the Darcy and Forchheimer values. The results of …

Lattice Boltzmann Study of the Interstitial Hydrodynamics and Dispersion in Steady Inertial Flows in Large Randomly Packed Beds
… from the linear (Darcy) regime to the inertial (Forchheimer) regime is quantified. Disorder is shown to play a critical role on dispersion in packed beds. In contrast to predictions based on regular periodic media, low porosity simulations for randomly packed beds predict a significant increase …

Experimental characterization of the Barree and Conway (2004) single-phase non-Darcy flow model in various hydraulic fracturing sands
… points out limitation to the validity of the Forchheimer equation. The Barree and Conway non-Darcy single-phase model fits the experimental data across the entire range of the pseudo-N[subscript Re] experimentally obtained. The minimum permeability could not be verified due to pressure …

A Study of Heat and Mass Transfer in Porous Sorbent Particles
… are compared with predictions from the Darcy-Forchheimer equation for media composed of different structure sizes. The developed methodology is also applied to CO2 diffusion studies in porous spherical particles of varying porosities. For the pore channels that are unresolved by the IBM …
