Experimental Investigation of Forchheimer Coefficients for Non-Darcy Flow in Conglomerate-Confined Aquifer [PDF]
A conglomerate-confined aquifer (CCA) plays an important role in affecting the safety and environmental protection during energy mining. In this study, the Forchheimer coefficients and associated seepage characteristics of the CCA were studied for different hydrogeological conditions via integrating theoretical analysis, hydromechanical experiment, and

A hybrid analytical/numerical model for the characterization of preferential flow path with non-Darcy flow. [PDF]
Due to the long-term fluid-solid interactions in waterflooding, the tremendous variation of oil reservoir formation parameters will lead to the widespread evolution of preferential flow paths, thereby preventing the further enhancement of recovery ...

Estimation of the Non‐Darcy Coefficient Using Supercritical CO2 and Various Sandstones [PDF]
AbstractNon‐Darcy flow (also known as high‐velocity flow, inertial flow, etc.) often occurs in the near‐well region of a reservoir during injection or production. This flow needs to be characterized and its origins fully understood, as it is a critical factor in reducing well productivity.

The Forchheimer equation is widely used in studying non-Darcy flow. Non-Darcy flow coefficient β in the Forchheimer equation is generally thought to be positive, and there are few studies on negative values. In this work, we performed seepage tests on sandstone samples with single, T-shaped, and Y-shaped fractures under different confining pressures ...

Study on the REV Size of Fractured Rock in the Non-Darcy Flow Based on the Dual-Porosity Model
For the problem of whether the representative elementary volume (REV) obtained in the Darcy flow is also applicable to the case of the non-Darcy flow, the study on the REV size within the non-Darcy flow is proposed tentatively.

Modelling laminar transport phenomena in a Casson rheological fluid from an isothermal sphere with partial slip in a non-Darcy porous medium [PDF]
The flow and heat transfer of Casson fluid from a permeable isothermal sphere in the presence of slip condition in a non-Darcy porous medium is analyzed. The sphere surface is maintained at a constant temperature. The boundary layer conservation
