| 摘 要： | 增加沸腾管入口段流动阻力是抑制沸腾管内流动不稳定性的主要措施之一。本文采用商用CFD软件CFX对带有微小节流件的沸腾管入口段进行计算分析，得到了计算该段摩擦阻力的关系式，并能与现有的实验数据吻合。

| Abstract: | One of the major measures to suppress flow instability in a boiling tube consists in increasing the flow resistance at the boiling tube inlet section. With the help of a CFD (computational fluid dynamics) software "CFX" computations and analyses have been performed of a boiling tube inlet section fitted with a tiny throttling element and a formula for calculating the friction resistance of that inlet section was obtained. The calculation results agree well with the experimental data. |
