粘性耗散是熔体在流动过程中由粘性摩擦力引起的机械能转换成热能的现象，它导致流动过程中流体的温度、粘度以及热量传递行为等发生变化，进而影响流体的流动特性。
(1) 涡流比滚流有较小的粘性耗散(viscous dissipation)，在压缩过 程中维持的时间较长，并且可利用活塞项燃烧室束口或活塞顶上特殊 形状，在上止点附近利用挤流与涡流相交，在燃烧室内...

结果表明：粘性耗散与塔架效应是引起尾涡变形的主要原因。
The result shows that viscidity dissipation and tower effect are main reasons of wake eddy distortion.
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.
