摘要
Based on the natural circulation experiment platform, the Flow Excursion of natural circulation in the narrow rectangular channel has been experimentally investigated on the natural circulation experiment platform. When the heating power comes up to a certain range, the natural circulation flow excursion occurs in the system, accompanied by the flow oscillation. The stability of the whole system increases with the increasing of the inlet sub-cooling, the pressure and the channel size. The stability curve of the system is drawn according to the sub-cooling and the phase change. It is discovered that there are 4 stages of flow excursion in the narrow rectangular channel, and the experience formula is proposed for the initial power of natural circulation flow excursion in the narrow rectangular channel. © 2016, Editorial Board of Journal of Nuclear Power Engineering.
