“…1 is the frequency of the sloshing, H L is a static liquid level, a is the radius of the container, g is the acceleration due to gravity and k 1 is the lowest root of the derivative of the first-order Bessel function and the value is approximately 1.84. Jet-induced rotary sloshing can be observed in a partially filled cylindrical container having a centered inlet nozzle and some drain nozzles (see, for instance, Madarame et al; 2) Yoshida et al 3) ). The inlet jet is injected through the inlet nozzle and the same volume is synchronously drained through the outlet nozzles so that the bath volume is kept constant.…”

Self-Induced Rotary Sloshing Caused by an Upward Off-Centered Jet in a Cylindrical Container

Self-induced rotary sloshing caused by an upward off-centered jet in a cylindrical container is numerically and experimentally investigated. Unlike the regular jet-induced rotary sloshing, the present off-centered case could contain components of higher fluctuation in the surface wave and the amplitude exhibits different values in various view angles. A simple geometrical model for the amplitude is established, by assuming the conservation of the angular momentum of the sloshing wave, and the predicted amplitude is tested against the experimental and computational results. Some results for the flow pattern, sloshing period, possible occurrence regime and trajectory of the peak point of the free surface swell due to the inlet jet are given.

“…In the same tank without the upper-innerstructure, self-induced sloshing was observed when an upward round jet on the tank axis created a surface swell at the impingement point. Jet behavior was investigated both experimentally and numerically [11]. Self-excited sloshing was observed in the cooling circuit of the French faster breeder reactor (FBR).…”

This paper presents for the first time observations of a self-induced sloshing phenomenon in the water-retaining weir model. Fast Fourier Transform method is used to detect the dominant frequency for the sloshing water. The characteristics of the sloshing water in terms of sloshing strength and frequency are experimentally studied for six different cases. Results show that both sloshing regions and sloshing strength depends on not only the water levels but also the inlet velocities, and the relationship between them is displayed in this paper. Different prediction models for sloshing frequencies are built and compared with the experimental results, with discussions of the differences between them. For higher water level sloshing region, a new factor is introduced to the Faltinsen's prediction formula, leading to a better agreement between prediction and experimental results. The mechanism of the self-induced sloshing is also discussed in this paper.
