WebFeb 15, 2007 · An alternative to Forchheimer's law is the Izbash equation, which states that the hydraulic gradient is a power function of the specific discharge (Bordier and Zimmer 2000;Moutsopoulos et al. 2009 ... WebMar 7, 2024 · 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 … WebWe study the generalized Forchheimer equations for slightly compressible fluids in porous media. The structural stability is established with respect to either the boundary data or the coefficients of the Forchheimer polynomials. A weighted Poincaré–Sobolev inequality related to the nonlinearity of the equation is used to study the asymptotic behaviour of … tauron serwisant 24h dom
