Permeability of Dual-Structured Porous Media
The effective permeability of dual-structured porous media has been determined through physical and numerical modeling. Example porous media consisting of a woven network of cylindrical bars overlaid by a network of spherical particles have been produced by a rapid prototyping technique. A glycerin-based solution, held in a pressurized reservoir, was forced through the porous samples. The resul...
متن کاملTransverse permeability of fibrous porous media.
In this study, the transverse permeability of fibrous porous media is studied both experimentally and theoretically. A scale analysis technique is employed for determining the transverse permeability of various fibrous matrices including square, staggered, and hexagonal arrangements of unidirectionally aligned fibers, as well as simple two-directional mats and simple cubic structures. In the pr...
متن کاملAbsolute Permeability Calculation by Direct Numerical Simulation in Porous Media
Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...
متن کاملExperimental Investigation of the Permeability and Inertial Effect on Fluid Flow through Homogeneous Porous Media
The value of the permeability in fluid flow through porous media is important for process investigation. In low Reynolds number, the classic Darcy’s law is suitable for simulation of fluid flow. In this paper, an experimental study for evaluation of preformed fiber permeability has been done. Also, the deviations from the classical Darcy law by experimental and numerical simulation of the N...
متن کاملMeasurements of Water Permeability in Unconsolidated Porous Media with Methane Hydrate Formation
Permeability is one of the key factors that determine the fluids flow capacity and production potential of hydrate deposits. In this study, an experimental setup is developed to investigate the flow properties of the porous media, and the permeabilities to water are measured in the unconsolidated porous media with or without hydrate deposition in the pores. A specialized method of precisely con...
