Darcy's Law is one of the most essential concepts in hydrogeology. Before moving on to more complex problems, students must first thoroughly understand the basic principles of one-dimensional fluid flow through saturated porous media that are embodied in Darcy’s Law. We believe that the best way for students to learn these principles is through experimentation. In this paper, we introduce an ex...

Darcy’s Law is the fundamental equation describing the flow of fluid through porous media including groundwater. It forms the quantitative basis of many science and engineering disciplines including hydrology, hydrogeology, soil science, civil engineering, petroleum engineering and chemical engineering. The year 2006 marked the 150th anniversary of the publication of Henry Darcy’s most famous t...

The present article discusses the solute transport process in steady laminar blood flow through a non-Darcy porous medium, as model for drug movement vessels containing deposits. Darcy–Brinkman–Forchheimer drag force formulation is adopted to mimic sparsely packed domain, and vessel approximated an impermeable cylindrical conduit. conservation equations are implemented axisymmetric system (R, Z...

Motivated by recent trends in spin coating operations chemical engineering which are exploiting nanomaterials, the present article investigates theoretically and numerically steady mass heat transfer von Karman swirling slip flow of a nanofluid from rotating disk touching to homogenous non-Darcy porous medium. The medium is simulated with Darcy–Forchheimer–Brinkman model. To track thermophoresi...

Abstract A seepage testing system was designed and a series of experiments on broken rock conducted using different original porosity conditions clay contents. The mass-loss process the change in water flow velocity were investigated. After test, non-Darcy characteristics tested through step-by-step pressure-reduced test. experimental results show that evolution during inrush could be divided i...

Vibrational mixed convection inside an open-ended cavity filled with a porous medium is investigated in this work. Vertical vibration on the left wall and buoyancy induced flow are considered. The effect of variations in governing parameters, such as vibrational Reynolds number, modified Rayleigh number, and the Darcy number on streamlines, isotherms, and the average Nusselt number is discussed...

A general form of the double porosity model of single phase flow in a naturally fractured reservoir is derived from homogenization theory. The microscopic model consists of the usual equations describing Darcy flow in a reservoir, except that the porosity and permeability coefficients are highly discontinuous. Over the matrix domain, the coefficients are scaled by a parameter representing the s...

We present a method to efficiently simulate coronary perfusion in subject-specific models of the heart within clinically relevant time frames. Perfusion is modelled as a Darcy porous-media flow, where the permeability tensor is derived from homogenization of an explicit anatomical representation of the vasculature. To account for the disparity in length scales present in the vascular network, i...
