Estimating of Non-Darcy Flow Coefficient in Artificial Porous Media [PDF]
Energies, 2022 This study conducted a radial flow experiment to investigate the existence of non-Darcy flow and calculate the non-Darcy “inertia” coefficient; the experiment was performed on seven cylindrical perforated artificial porous media samples.

Characterization of a Non-Darcy Flow and Development of New Correlation of NON-Darcy Coefficient
Energies, 2022 Darcy’s law has long been used to describe the flow in porous media. Despite the progress that took place in oil production industry research, it became clear that there is a loss of pressure, especially in the area near the wellbore region, where Darcy ...

Numerical simulation of the free surface and water inflow of a slope, considering the nonlinear flow properties of gravel layers: a case study [PDF]
Royal Society Open Science, 2018 Groundwater is an important factor of slope stability, and 90% of slope failures are related to the influence of groundwater. In the past, free surface calculations and the prediction of water inflow were based on Darcy's law.
