摘要
利用 MATLAB数值计算软件对毛管各管段建立的一组非线性方程组进行了求解 ,并采用 MATLAB语言集成开发环境编制了毛管水力分析程序 ,通过建立的人机交互界面实现了参数的设定与数据的分析 .结果表明 ,随坡度值增大 ,灌水均匀度先增后减 ;提高毛管进口水头 ,灌水均匀度增加 ;随流态指数的增大 ,灌水均匀度递减速度加快 ;滴头间距越长 。
The mathematical software of MATLAB is used to solve a group of nonlinear equations with respect to the parameters of a lateral segment and the integrated development environment of the MATLAB language is adopted to develop a program for lateral hydraulic analysis. The setting of parameters and analyzing of data are realized by the man-machine interaction. The results indicate that by increasing the lateral gradient, the emission uniformity is increasing first and decreasing afterwards. The emission uniformity increases as the inlet head being increased. When increasing the flow pattern exponent, the decreasing rate of emission uniformity augments and if the spacing between emitters is longer, the emission uniformity will be worse.
