因次分析是一种重要的数学建模方法,广泛应用于化工原理中与湍流有关的物理现象的无因次数群关联式的建立。经典化工原理在因次分析过程中采用手算法进行符号运算,非常烦琐;本文基于MATHEMATICA~软件强大的符号运算功能,给出了一个因次分析程序,用来进行因次分析中的这些烦琐而重复的计算。本文还给出了该程序的若干应用实例。
It is an important mathematical modeling method that is widely used in the establishment of the dimensionless group-correlativity of chemical phenomena related to turbulence in chemical engineering. Classic chemical principles in the process of factor analysis using the hand algorithm for symbolic operations, very cumbersome; Based on MATHEMATICA ~ software powerful symbolic computing functions, gives a factor analysis program for the analysis of these cumbersome And repeated calculations. This article also gives a number of examples of the application.
