Comparison of Binomial and Power Equations in Radial Non-Darcy Flows in Coarse Porous Media
Analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. Darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. Non-linear equations are classified into power and binomial equations. Binomial equation is more accurate in a wide range of velocit...

متن کاملMultiscale Simulation of Non-darcy Flows
In this work we present control volume multiscale methods which address problems on the interaction between pore scale and Darcy scale. For the case when linear equations govern the flow on the pore scale our solution converges to semi-analytical solution. Moreover, the method also extends to non-linear problems governed by NavierStokes equations. We show numerical results illustrating the appl...
متن کاملDouble dispersion effects on natural convection heat and mass transfer in non-Darcy porous medium
The problem of hydrodynamic dispersion in non-Darcy free convection heat and mass transfer from vertical surface embedded in a porous medium has been presented. The Forchheimer extension is considered in the flow equations. The flow, temperature and concentration fields in Darcy and non-Darcy porous media are observed to be governed by complex interactions among the diffusion rate Le, buoyancy ...
متن کاملNon-Darcy Mixed Convection with Thermal Dispersion-Radiation in a Saturated Porous Medium
In the present work melting with thermal dispersion and radiation on non-Darcy, mixed convective heat transfer from an infinite vertical plate embedded in a saturated porous medium is studied. Both aiding and opposing flows are examined. Forchheimer extension for the flow equations in steady state is considered Similarity solution for the governing equations is obtained .The equations are numer...
