Abstract

Abstract

Flow instability of natural circulation under rolling motion condition was studied experimentally in this paper.The results showed that the rolling motion might cause the early occurrence of the OFI of natural circulation and changed the types of flow instability.Flow oscillation caused by the rolling motion might overlap with the density wave oscillation.The system stability decreased with the increasing of the rolling amplitude and frequency.There were two stable regions under rolling motion condition,between which there is an unstable region.
- Rolling motion,
- Natural circulation,
- Flow instability
