Self-induced sloshing caused by an upward round jet impinging on the free surface
- Univ. of Tokyo, Tokai, Ibaraki (Japan). Nuclear Engineering Research Lab.
The demand for compact design of FBR made it necessary to study the interaction between high speed coolant flow and the free surface. Self-induced sloshing was found to occur with an upward round jet making a surface swell at the impinging point. The conditions under which the sloshing occurred were investigated experimentally together with the sloshing modes and frequencies. Without exception the induced mode had only one diametrical node, which was accompanied by the lateral motion of the swell. The mode was replaced by lower one with increasing the inlet-surface distance and the velocity, the reason of which was explained by the following assumption; the oscillation of water columns on both sides of the jet connected by a virtual cross flow through the jet, i.e., jet-flutter, was coupled with the sloshing and supplied energy to it.
