Abstract

The splashes of a highly viscous fluid (glycerol) resulting from its pulsed displacement from a gap between two rapidly approaching disks are studied. It is found that, outside the disks, the splash has the form of a thin film bounded by an annular rim. A physical model of the splash is formulated, and analytical solutions describing its trajectory are given. The calculation results are compared with experimental data. The effects of fluid viscosity, surface tension, and film breakdown are analyzed. It is shown that the key influence on the splash development scenarios is exerted by surface tension of the film connecting the rim to the disks.

粘性液体的圆形飞溅

研究了高粘度流体（甘油）从两个快速接近的圆盘之间的间隙中脉冲位移所产生的飞溅。研究发现，在圆盘外，飞溅的形式是以环形边缘为边界的薄膜。研究建立了飞溅的物理模型，并给出了描述其轨迹的解析解。计算结果与实验数据进行了比较。分析了流体粘度、表面张力和薄膜破裂的影响。结果表明，连接边缘和圆盘的薄膜的表面张力是影响飞溅发展情况的关键因素。

期刊介绍： Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
