Self-induced rotary sloshing caused by an upward round jet in a cylindrical container

Abstract

Jet-induced rotary sloshing of a Newtonian fluid in a partially filled cylindrical container is numerically and experimentally visualized to investigate a flow pattern inside the rotary sloshing wave. Visualization techniques employed in this study include Computational Fluid Dynamics (CFD) and Particle Image Velocimetry (PIV). Result for the sloshing period is compared with the theoretical result of a small time-harmonic irrotational flow of an inviscid and incompressible fluid, and several results for 3D view of the rotary sloshing and the velocity vector in the vertical and horizontal cross-sections are given.

Numerical Simulation on a Horizontal Flow Pattern of Jet-induced Rotary Sloshing in a Cylindrical Container

“…We note that the potential solution of Eq. (1) is obtained from the pure rotary sloshing without the inlet jet, and the preceding article 2) shows that the potential solution is in a good agreement with the jet-induced rotary sloshing except for near the free surface wave, the wall of the container and inside the inlet jet. The analytical period of the rotary sloshing, T 1 ϭ2p/w 1 , exhibits the value of 0.483 (s) for H L ϭ10 (cm) and, hence, is found to be in nice agreement with computationally and experimentally measured values of 0.475 (s) and 0.480 (s).…”

“…1,2) The inlet jet is injected through the inlet nozzle and the same quantity is synchronously drained through the outlet nozzles so that the bath volume is kept constant (Fig. 1).…”

“…role in accelerating a chemical reaction. The preceding article of Ueda et al 2) was numerically and experimentally investigated for the flow field inside the jet-induced rotary sloshing and compared with the inviscid solution of the small amplitude. In order to compensate the preceding study, the aim of this paper is to numerically visualize the variety of the horizontal flow pattern in the various z-planes in Fig.…”

Numerical Study of Self-Induced Rotary Sloshing Caused by an Upward Periodic Jet in a Cylindrical Container

“…Self-induced rotary sloshing in a partially filled cylindrical container can be caused by an inlet jet (see e.g., the references [1][2][3][4][5][6][7][8][9][10] ). Figure 1 shows the previous experimental photograph of the sloshing caused by an upward constant jet and its simple illustrative example.…”
