多工况的遗传算法校正管道摩阻系数

Multi-mode Genetic Algorithm for Correction of Pipe Friction Factor

用遗传算法校正摩阻系数的过程中,由于测量数据的不足往往存在多解的情况,而瞬时分析方法又不适用于大型的管网。通过对真实管网的不同运行工况进行模拟并收集到大量的管网运行数据,在此基础上建立了不同工况的遗传算法摩阻系数校正模型,算例显示其计算结果与实测值较为接近。

In the course of using genetic algorithm for correction of pipe friction factor,multi-resolution often is found for the insufficient measuring data,while the transient analysis is not suitable to large-scale pipe network.Through simulation to different operating modes of actual pipe network,a lot of operating data were collected.Based on this,correction model for friction factor under different operating modes was built by means of genetic algorithm,the result of calculation examples shows that the calculating values are close to the real values.
