Approaches for the experimental and numerical study of the distinctive features of fluid flow through media with double porosity that are based on micromodels of porous media and microfluidic technologies are proposed. The optic microscopy and tracer flow visualization methods are used to study experimentally fluid flow through model media. The numerical approach is based on the three-dimensional boundary element method accelerated with the use of the fast multipole method on heterogeneous computational architectures. The effect of structure parameters of micromodels on the flow distribution between the domains with different porosities is studied. Variation in the longitudinal and transvers velocity components in small and large pore channels is considered as functions of their geometric parameters and volumetric flow rate.

双孔隙介质微模型中流体动力流动的研究

摘要—

提出了基于多孔介质微模型和微流体技术的流体在双孔隙度介质中流动的独特特征的实验和数值研究方法。光学显微镜和示踪流可视化方法用于实验性地研究通过模型介质的流体流动。数值方法基于三维边界元方法，在异构计算架构上使用快速多极方法加速。研究了微模型结构参数对不同孔隙率域间流动分布的影响。小孔和大孔通道中纵向和横向速度分量的变化被认为是其几何参数和体积流量的函数。
