多孔非均匀出流问题数学模型研究
Research on mathematical model of non-uniform outflow in irrigation pipeline system with malti-hole
【摘要】 根据广东省台山市都斛镇水稻田控制排灌田间工程试验区的实测资料 ,探讨了在已定工作水头和输水管管径的条件下 ,不同出水口开启状况下各给水栓出流量的数学计算模型 ,用最速下降法计算非线性方程组的方法对这一数学模型进行了求解 ,并与实际观测情况进行了比较和分析 ,通过这些计算探索自动给水栓灌溉系统的设计方法 ,为这套灌溉系统在将来生产实践中的优化设计及应用打下理论基础
【Abstract】 Combining the controlling irrigation_drainage engineering item for paddy field in Taishan city of Guangdong province, the authors puts the stress on the questions of non_uniform clearance on auto_hydrants for irrigation system. Applying the steepest descent algorithm to work out the problem of system of nonlinear equations. This issue works on the mathematical analysis method on different conditions of the holes’ open and close. Therefore it affords ways of scientific calculation for improving the irrigation system.
