Application of Order of Magnitude Analysis and Theory of Analogy in Heat Conduction and Analysis
-
摘要: 運用數量級分析和相似原理對第一類邊界條件下不穩態導熱問題進行了求解,并從5個方面分析了熱層與邊界層的類似性。提出了導熱雷諾數、阻熱系數及層態和紊態導熱的概念,說明了導熱雷諾數的物理意義,導出了阻熱系數與導熱雷諾數的關系,分析了層態和紊態導熱的特點。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.
