摘要
依靠量纲分析得到体系的无因次准数是化学工程分析的重要手段,而正确选择体系的特征物理量是其中的重要一环。本文以化工常见的体系为例,说明体系特征量的个数和选择方法,为一般的量纲分析过程提供了有益的指导原则。
Acquiring the dimensionless groups in a chemical engineering system via dimensional analysis is an important technique in chemical engineering, and the correct selection of characteristic parameters from the system is an important link in this procedure. This article presents 3 typical examples to illustrate the rule on the number of characteristic parameters and the guidelines for choosing them. The summarized tips are useful as the dimensional analysis is applied to more general cases.
