摘要
对国内原创全射流喷头组合喷灌进行研究后,提出了一种分析处理喷头水量分布数据以实现三维可视化编程的方法.研究表明,MATLAB语言可以方便可靠地将喷头径向水量分布数据转换为网格型数据,并绘制出单喷头和喷头组合的三维水量分布图.通过插值叠加求出各网格点总降水深,求出不同组合间距系数下的全射流喷头组合均匀系数,实现计算结果可视化.根据模拟分析,提出了组合间距系数值:正方形布置时为1.2,各喷头均匀系数平均值为82.4%;三角形布置时为1.5,各喷头均匀系数平均值为85.7%.另外认为,MATLAB语言编程进行喷头喷洒分析具有功能强大,方便快捷,可视性强等优点,适用于任何喷头水量分布的分析.
The complete fluidic sprinkler was originally analyze the data of water distribution, The data can be developed in China. A software was presented to made visible in multidimensional orientation as a result. By using MATLAB it was proved that the radial data can be changed into net data conveniently and reliably, Three-dimensional water distribution pictures for sprinkler and combined sprinklers were drawn by MATLAB. According to the test data, the total water depth of net point was calculated using superposition method. Then the combined uniformity coefficient of the complete fluidic sprinkler was simulated in different combined spacings, After the simulation, combined spacing coefficient was chosen as 1.2 in the rectangular combination, and 1.5 in the triangular combination. The average uniformity coefficients are 82.4% and 85.7% respectively. A case study shows that MATLAB is reliable for simulating water distribution in sprinkler irrigation.
