- 中文摘要: 本文之目的在於回顧體積平均方法,此方法最主要的功能有二:(l)提供對多相系統中之輸送方程式很嚴謹的推 導,(2)可理論推測有效輸送係數,譬如有效熱導係數,軸向和徑向分散係數等。本方法另一功能是提供對發生在一 長度刻度較大範圍內,臂如一固定觸媒床, 一很嚴謹的方法以?明相關之物理現象。
- 英文摘要: The purpose of this article is to provide a brief review of the method of volume averaging which has two principal objectives: (1) the rigorous derivation of spatially smoothed transport equations for multiphase systems, and (2) the theoretical prediction of effective transport coefficients such as the effective thermal conductivity, iongitudinai and lateral dispersion coefficients, etc. Another objective of the method of volume averaging is to provide a rigorous means for relating physical phenomena that occur over a wide range of length scales such as those encountered in packed bed catalytic reactors.
