矩形窄缝自然循环密度波不稳定特性实验研究
Experiment Study of Density Wave Instability of Natural Circulation in Narrow Rectangle Channel
摘要
Abstract
The experimental study was performed to investigate the flow instability in a natural circulation system by using deionized water , which gained the changeable situation of the flow rate in the narrow rectangle channel at the size of 2 mm and 5 mm . The analysis results show that the periods of wave with 2 mm and 5 mm narrow rectangle channel are 4‐5 s and 5‐7 s respectively ,the symmetrical characteristic of the amplitude of 2 mm is not good as the 5 mm it is ,and the periods of the 2 mm and 5 mm increase with the heating power .With the heating power increasing ,flow excursion phenomenon happens in the channel at the size of 2 mm ,and the characteristic of density w ave w eakens .关键词
