Some fractal characters of porous media
WebFeb 1, 2009 · In this study, we summarized some basic characters of fractal porous media, including the fractal pore or particle size distribution, pore or particle density function, the fractal dimensions for the pore and solid phases, and their relations. The geometric porosities vs. the fractal dimensions and microstructures of porous media were reviewed … WebThis model can be used to analyze the effective stress effects on pore size of porous media and fractal dimension of the pore structure distribution. 1. According to the fractal model …

WebJun 1, 2009 · 1.. IntroductionFractal porous media have been studied extensively for more than two decades since Mandelbrot’s pioneer work [1].Katz and Thompson [2] used scanning electron microscopy and optical data to show that the pore spaces of several sandstones are fractal geometries. Fractured rocks [3] and fragmented porous media [4] … WebAbstract. In this paper, a unified model for describing the fractal characters of porous media is deduced. The theoretical predictions from the proposed unified model are compared …
WebIn addition, the present work reveals that the relative permeability depends not only on saturation but also on the two fractal dimensions, pore fractal dimension (at porosity … WebWe consider the fractal media as special ("fractional'') continuous media. We discuss the possible experimental testing of the continuous medium model for fractal media that is …
WebGiven Eq. ( 4.19 ), which relates the fractal dimensionality of the pore space to the porosity, and their assumed values r m / r 0 ≈10 4, their fractal dimensionality range from 2.57 to … WebFeb 1, 2024 · Tight porous media are mainly composed of micro/nano-pores and throats, which leads to obvious microscale effect and nonlinear seepage characteristics. Based on the capillary bundle model and the fractal theory, a new nonlinear seepage equation was deduced, and a further fractal permeability model was obtained for oil transport in tight …
WebIn mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension.Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly …
