摘要
一、前言 近年来高温气冷堆的研究受到国内外的广泛重视,高温气冷堆系统中的关键设备之一是蒸汽发生器,这种蒸发器通常由并联螺旋管构成。众所周知,蒸汽发生器并联蒸发管在设计不当时容易发生动态流动不稳定性,即流量脉动。流量脉动会引起系统控制问题,甚至导致发生蒸发管烧毁事故,因而必须避免流量脉动的发生。到目前为止。
This paper presents an experimental study of two-phase flow instability in a parallel helical coil tube system. Through the experiments the stability boundaries of the system are determined. The differences between the stability boundaries obtained with a single channel system and a parallel channel system respectively are investigated.
