WebJan 15, 2024 · The definition of \(\chi\) allows extracting the effect of the porous media structure on diffusive fluxes from a fluid specific impact. Thus, \(\chi\) is a sole property of the porous media structure, and we consider it a function of porosity \(\theta\) and the topology of the void space \(\chi = f(\theta , \text {topology})\) .
Webporous media. The direct method can, however, be used in the relatively simple problems of Taylor dispersion in a tube or transport in spatially periodic porous media (Koch 1986). Here, the average reduces to an average over a cross-section or a unit cell, and the closure problem is absent. (Simple is used here in a conceptual sense; Webwhere ϕ is the porosity, r is the pore radius, and c is the geometric factor that accounts for the shape, connectivity, aspect ratio of pores, and tortuosity of the pores and depends on the model. The structure of a pore space is illustrated in Figure 1.Equation 1 indicates that the permeability is very sensitive to the pore radius. A porous medium usually contains pores …
