基于Matlab的供水管网余氯衰减模拟

Modeling Residual Chlorine Decay in Water Distribution Network Based on Matlab

建立了基于拉格朗日时间驱动法的供水管网余氯衰减微观模型,使用具有科学计算和绘图功能的Matlab软件和Access数据库建立了供水管网余氯衰减动态模拟系统。该模拟系统不仅可以对不同工况、不同时刻供水管网的余氯衰减进行动态模拟,而且还可以动态绘制管网余氯等值线图和等值面图。经算例验证,该模拟系统可准确地进行管网余氯衰减动态模拟,通过分析模拟结果和系统绘制的动态余氯等值图可以全面反映不同时刻供水管网所有节点的余氯衰减状况。

A decay model of residual chlorine in the water distribution network was established using the Lagrangian time-driven method. The network model is based on the program Matlab which computes and generates figures, and the program Access which provides a database. The system carl simulate the decay of residual chlorine in the network dynamically, and also generate 2-D contour maps of residual chlorine. After analyzing the simulation results and contour maps, the model carl reflect the decay of residual chlorine at all nodes of the network under different hydraulic conditions and during different time periods.
