摘要
用相似准则、量纲分析和π定理分析了可压缩的非等温和非牛顿流体流动的相似性.当π_1,π_2,…,π_n与所对应的各准数基本相等时,可认为这两种流体的流动是相似的.
The flow similarity of compressible non -isothermal and non-Newtonian fluids was analyzed by similarity rule , dimensional analysis and π- principle . When π1 ,π2 ,…,πn were similar to those of corresponding dimensionless num- bers respectively , the flows of these two fluids were regarded as similarity .
