Resistance Characteristics of Single-Phase Flow through Porous Media

National Key Laboratory of Bubble Physics and Natural Circulation, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 研究了高雷诺数条件下多孔介质内单相流阻力特性。采用孔隙有效雷诺数(Re)修正了惯性项系数R_f的表达式,得到多孔介质中单相流阻力关系式,对影响多孔介质内单相流阻力特性的因素进行了分析。试验结果表明,惯性项系数R_f与渗透率K、孔隙率ε和Re有关。

Abstract: In the present paper, the resistance characteristics of single-phase flow under the high Re number is studied.. By modifying the inertia factor with Re, the resistance correlation of single-phase flow in porous media has been obtained. The chief factors which affect the resistance characteristics of single-phase flow in porous media have been discussed. The experiment indicates that the inertia factor is affected by permeability and porosity of porous media, as well as Re.
