螺旋泵可用来输送高粘性液体,该过程中由于液体的温度升高而粘度降低,因而其粘性耗散不能忽略。
Screw pumps can be used to highly viscous liquid. Viscous dissipation cannot be neglected during such pumping because it causes the temperature of liquid to rise and its viscosity to decrease.
实验表明:空气-高粘性液体和空气-起泡液体的气、液两相流型与通常的空气-水系统的流型极不相同。
Tests showed that the two phase flow patterns of air-highly viscous liquids and air-foaming liquids are very different from that of air-water.
在做颗粒分离实验时,研究人员在一块大乐高板上插满了圆柱状乐高钉,然后把板垂直放入盛满粘性液体甘油的鱼缸。
For the particle-separation experiments, the researchers covered a large Lego board with cylindrical Lego pegs and placed the board vertically in a fish tank filled with glycerol, a viscous liquid.
