MathCAD2001在复杂流体流动计算中的应用

The application of MathCAD2001 in the calculations of the complex fluid flow

在流体流动计算中经常会遇到求解非线性方程或非线性方程组等复杂的数学问题,使用传统的手工计算或计算机编程计算都是不方便的。本文开发了使用MathCAD2001解决复杂的流体流动计算问题的方法。首先对流体流动过程进行分析, 得出需要求解的数学模型。然后在MathCAD2001中选择适当的求解函数进行求解。该方法过程简便、概念清楚、使用方便, 便于教师课堂教学使用。

In the calculations of the fluid flow, complicated mathematic problem, such as non-linear equations or sets of non-linear equations, are using met. It＇s less convenient to use traditional manual or computer program to solve these problems. This paper developed the methods to solve the complex mathematic equations of the fluid flow with MathCAD2001. First the mathematic models were obtained by analyzing the fluid flow process. Then the proper functions in the MathCAD 2001 will be chose to solve the mathematic models. This method is simple in process, clear in concept and convenient for application. And it is suitable for teachers to use in the classroom.
