We have developed a new technique (based on our Cartesian-representation method) to describe hydrodynamic interactions of a spherical particle with an undeformable planar fluid-fluid interface under creeping-flow conditions. The interface can be either surfactant-free or covered with an incompressible surfactant monolayer. We consider the effect of surface incompressibility and surface viscosity on particle motion. The new algorithm allows to calculate particle mobility coefficients for hydrodynamically coupled particles, moving either on the same or on the opposite sides of the interface.
我们开发了一种新技术(基于我们的笛卡尔表示方法),用于描述在蠕动流条件下,球形颗粒与不可变形平面流体-流体界面之间的流体动力学相互作用。该界面可以是无表面活性剂的,也可以覆盖不可压缩的表面活性剂单层。我们考虑表面不可压缩性和表面粘性对颗粒运动的影响。新算法允许计算在相同或相反界面侧移动的流体动力耦合颗粒的迁移率系数。
