摘要

在本文中,我们考虑了亲水和疏水液体在毛细管中的运动。众所周知,这类流体的流动结构取决于一系列条件。控制参数的正确选择对于控制流向不同模式的转换具有重要意义。过滤问题中最重要的问题是过滤过程中位移锋的形态稳定性。一般认为只要控制毛细数就足以改变流动型态。本文表明,还可以单独提出另一个参数,即分离压力。如果能够找到影响楔入压力的机理,那么就有可能通过改变射流厚度来有效控制流动,并控制聚类过程(射流分裂成液滴)。本文表明,这种机理可能是碳氢化合物分子与纳米颗粒的相互作用。

Flow of oil nanoclusters in a porous medium capillary
   In the article, we consider movement of hydrophilic and hydrophobic liquids in a capillary. It is known that structure of flow of such fluids depends on set of conditions. The issue of correct choice of control parameters is of great importance for controlling the transition of the flow into different modes. The most important issue in the filtration problem is morphological stability of displacement front during filtration. It is generally assumed that it is sufficient to control the capillary number to change the flow regimes. The article shows that another parameter can be singled out, which is the disjoining pressure. If mechanisms of influence on wedging pressure can be found, then it is possible to control effectively flow by changing thickness of jet and to control the process of clustering (splitting of jet into droplets). In the article, it is shown that such mechanism can be interaction of hydrocarbon molecules with nanoparticles.
