本文提出了关手应用计算机研究管系瞬变流的许多概念。文章直接指导如何应用微机,但不为此特定目的所限。内容包括处理系统数据的程序编制原理,以及应用特征线法作计算程序时实现一定存储和获得一定计算效率的思想。讨论了规定时间间隔法的替换方案,即交错网格法及其代数处理方法。还强调了对摩阻项所作的简单改进。集中研究了水利系统中影响压力波生成的两种常用元件,即串联连接件和损失元件,以便提供一种改进的直观研究其响应特性的方法。提出了有初始过流和无初始过流情况下的方程式和图表。最后,举出一实际系统失事的例子,强调水利系统设计中非恒定流直观研究的重要性。
This paper presents many concepts related to the use of computers to study transient flow in pipelines. Article direct instruction on how to use the computer, but not for this specific purpose. The content includes the principle of programming system data processing, as well as the application of the characteristic line method for calculating the program to achieve certain storage and to obtain a certain amount of computational efficiency. An alternative to the prescribed time interval method is discussed, namely the staggered-grid method and its algebraic processing method. It also highlights the simple improvements made to friction. Two types of common components that affect the generation of pressure waves in water systems, namely series connections and loss components, are focused on providing an improved way to visually investigate their response characteristics. The equations and graphs with initial overcurrent and without initial overcurrent are presented. Finally, an example of an actual system crash is cited, emphasizing the importance of an intuitive study of unsteady flow in water system design.
