| 摘 要： | 应用自适应网格法对长输管道的水力瞬变进行了计算,通过求解水击偏微分方程,在解的大梯度区自动加密网格。以一个站间管道的末段为例,用特征线法和自适应网格法进行了计算。计算结果表明,自适应网格法能够更准确地捕捉到水击压力波的前沿位置。

| Abstract: | In the study, the adaptive grid method is first used to calculate the hydraulic transient flow of long distance pipelines. Through the uncoil partial differential equation, the grid is added by itself in big gradient. Calculations on an end section of a pipeline with adaptive grid method and characteristic line method are carried out. The calculation result indicates that with the adaptive grid method, the front position of water hammer more exactly can be obtained. |
