补充资料:粘性流体
      粘性效应不可忽略的流体。可忽略粘性效应的流体称为理想流体。流体由大量分子所组成。相邻两层流体作相对滑动或剪切变形时,由于流体分子间的相互作用,会在相反方向上产生阻止流体相对滑动或剪切变形的剪应力,称为粘性应力。实验证明,粘性应力同粘性系数(即粘度)和相对滑动速度有关(见牛顿流体)。
  
  由于流体中存在着粘性,流体的一部分机械能将不可逆地转化为热能,并使流体流动出现许多复杂现象,例如边界层效应、摩阻效应、非牛顿流动效应等。自然界中各种真实流体都是粘性流体。有些流体粘性很小(例如水、空气),有些则很大(例如甘油、油漆、蜂蜜)。当流体粘度很小而相对滑动速度又不大时,粘性应力是很小的。即可看成理想流体。理想流体一般也不存在热传导和扩散效应。实际上,理想流体在自然界中是不存在的,它只是真实流体的一种近似。但是,在分析和研究许多流体流动时,采用理想流体模型能使流动问题简化,又不会失去流动的主要特性并能相当准确地反映客观实际流动,所以这种模型具有重要的使用价值。
  
  理想流体和完全气体是完全不同的概念,前者指流体没有粘性,后者指气体有完全的可压缩性。(见边界层,流体阻力,非牛顿流体力学)
