WebThe study consists of two parts. In this part we briefly recall Darcy’s and Forchheimer’s laws and address the issue of detecting transition between ranges of their applicability. Then we describe the experiment and discuss 8 different ways to process measurement data, four for Darcy’s, and four for Forchheimer’s models. Web4.1.What are the assumptions for Darcy’s law to be valid? Discuss each of them. Solution 4.1 The key assumptions are 1. Steady flow. The flow is constant over time. 2. Laminar. Only applied to non-turbulent flow with Reynolds number less than about 1. 3. Inviscid. The viscosity remains constant so temperature and pressure are constant. 4.
Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences. It is analogous to Ohm's law in electrostatics, linearly relating the volume flow rate of the fluid to the hydraulic head difference (which is often just proportional to the pressure difference) via the hydraulic conductivity.
