将不混溶的硅油和水容纳在圆柱形容器中。它们的体积比，称为体积比，在很宽的范围内变化。将容器突然旋转，用粒子图像测速仪（PIV）和激光多普勒测速仪（LDV）测量两种液体的流速。流动建立时间定义为从旋转开始到血管中建立稳态的时间段。提出了流体建立时间与体积比、旋转角频率和液体物理性质的经验公式。还观察到硅油-水界面的变形，以证实从速度测量获得的结果。
Immiscible silicone oil and water were contained in a cylindrical vessel. The ratio of their volumes, referred to as the volume ratio, was varied over a wide range. The vessel was suddenly set in rotation, and the flow velocities of the two liquids were measured with particle image velocimetry (PIV) and laser Doppler velocimetry (LDV). The flow establishment time was defined as the period from the start of rotation to the moment at which a steady state is established in the vessel. An empirical equation for the flow establishment time was proposed as a function of the volume ratio, the angular frequency of rotation, and the physical properties of the liquids. The deformation of the silicone oil-water interface was also observed to confirm the findings obtained from the velocity measurements.
