摘要
本文建立了基于弯曲流道的颗粒堆积型多孔介质内流体流动的毛细管束模型,并在低雷诺数、低空隙率范围内对颗粒层多孔介质内的渗透率、阻力特性等进行了研究,结果表明弯曲流道毛细管束模型适合于计算颗粒层多孔介质内流体流动。
A model of capillary tube bundles for tortuous streamtube proposed based on hydraulic tortuosity factor in unconsolidated porous medium with spherical particles. A relationship set up hydraulic tortuosity factor with geometric parameter in this model. The model predictions are found to be in good agreement with the available experimental data.
