化工原理流体流动过程的计算机辅助计算

Computer-aided calculation of fluid flow in unit operations

流体输送过程为化工原理课程中的基础部分,其计算过程繁琐、图示过程众多,采用传统的板书讲解方式难以达到较好的授课效果。本文利用MATLAB语言强大的运算与图形表达功能,剖析了流体流动过程中的典型例题,给出了计算机辅助计算的具体思路和方法。此外,本文也给出了利用计算机对本单元实验数据进行自动处理的方法。这些计算机辅助计算过程,大大增强了教学过程的直观性和可视性,加深了学生对流体流动过程单元的理解。

As the emphasis and basis of unit operations, fluid flow has such features as complex calculation procedures and various graphic problems, so it is difficult to achieve good teaching effect only by writing on blackboard. In this paper, on the base of powerful calculation and graph ability of MATLAB, the typical examples in fluid flow are analyzed and the corresponding ideas and methods of computer-aided calculation are given. Besides, a procedure of calculating experiment data with the aid of computer is proposed also. In all, with the assistance of computer, the visibility of teaching program can be enhanced and therefore the students can understand this unit operation more deeply.
