摘要
二维流动是水泵、水轮机等流体机械中的一种常见流动。二维流动划分为在力学性质上有重要区别的两大类:旋流与势流。本文作者介绍了一种国外报导的区分这两种不同流动的新方法,并分析了这一新方法的特点,通过实例显示这一方法的价值。该方法与传统方法相比较具有计算简捷、快速的优点,并将为国内技术人员提供一种新的流场分析工具。
Two-dimensional flow occurs in a large number of pump and turbine parts. Two-dimensional flow consists of two types with distinct mechanical features： rotative flow and potential flow. Authors of this paper display a novel way based on foreign literatures to distingwish the flow pattern. This method, has the advantages of simply and quick calculation, and can be a new tool for flow field analysis.
