摘要
从不定常偏微分方程组出发,采用特征线方法,对多管路系统的不同管道,使用不同的时间步长计算了水锤现象。由于步长随需要和管长不同而异,使计算最大大减少,保持了计算精度,提高了计算效率。数值模拟结果是满意的,可为工程中管道系统的设计及防护提供参考和依据。
The results of water hammer for multi - piping system is presented the water hammer in complicated pipes has been computed by characteristic line -method. To improve the accuracy of numerical calculations, Variable step with multipipes are used. So the computational work are greatly reduced. Some computable results are satisfactory. It will provide the foundation to choose plan for piping desin and piping protection.
