VALIDITY OF DARCY AND FORCHHEIMER EQUATIONS OF POROUS MEDIUM FLOWM. THIRUVENGADAM, G.N. PRADEEP KUMAR AND D. SIVAKUMAR
This paper presents a review of validity of experimentation; analysis and application of porous medium flow equations of Darcy and Forchheimer, which are critically reviewed theoretically and experimentally. The drawbacks observed while computing the coefficients of these equations have been critically analyzed. New equations have been obtained in terms of measurable quantities and compared with experimental data in laminar and turbulent regimes. Experiments have been conducted on porous media of large spread of sizes in parallel flow permeameter, the experimental results are compared with Darcy and Forchheimer equations, and its validity is checked.
