数量级分析和相似原理在导热中的应用

Application of Order of Magnitude Analysis and Theory of Analogy in Heat Conduction and Analysis

    摘要
  • 摘要: 运用数量级分析和相似原理对第一类边界条件下不稳态导热问题进行了求解,并从5个方面分析了热层与边界层的类似性。提出了导热雷诺数、阻热系数及层态和紊态导热的概念,说明了导热雷诺数的物理意义,导出了阻热系数与导热雷诺数的关系,分析了层态和紊态导热的特点。

     

    Abstract: One dimensional unsteady problem with 1st kind of boundary condition was solved by using the order of magnitude analysis and theory of analogy. The similarity of heat layer to boundary layer was analysed from five aspects.
