The effect of permeability on Darcy-to-Forchheimer flow transition
WebJul 13, 2024 · Existing models are built upon to develop new ones. As a foundational model in porous media flow, the Darcy flow model has been built upon by many researchers. The groundwater flow equation evolved from the Darcy equation. Dupuit–Forchheimer built upon it to develop the simplified forms for both the confined and unconfined aquifers … Web10.6.

WebSep 1, 1997 · Forchheimer drag makes only 5.48 % of the total drag. Such a fraction of Forchheimer drag is incredibly low as compared to 11.15% from the present result. It is noted that Ergun's correlation [5] gives a fraction of Forchheimer drag as large as 39.81 % for granular beds under the same parameters. In their work, Coulaud et al.
