“…This kind of system is mostly studied using experimental methods. [6,7] It is necessary to establish an effective mathematical model to study the dynamics behaviors of the liquid-filled coupling system using an analytical method. Yin et al [8] and Ma et al [9] expanded the velocity potential function at the free surface of the liquid and obtained a group of generalized modal coordinate nonlinear equations by the Lagrange function to make a theoretical analysis.…”

The nonlinear governing equations of the liquid sloshing modals in a cylindrical storage tank are established. Through analytical analysis, the analytical expressions of the solutions of this kind of system are obtained. With different parameters, the dynamical behaviors of the solutions are different from the trivial ones. To prevent system instability, two selection principles that the stiffness equations are positive-definite and the nonlinear terms of the system are not regenerative elements are given. Meanwhile, numerical simulations are also given, which confirm the analytical results.

“…(iii) Why are the low-frequency, three-dimensional gravity waves excited by the high-frequency external forcing? The third problem is the main focus of the present paper which describes oscillationinduced jets, jet instability and jet-induced sloshing by lateral single-point forcing of the sidewall of a water-filled container (Peng, Wang & Lee 2005;Peng et al 2006Peng et al , 2008Peng & Lee 2009). The interactions between the free surface and submerged vortical flows have been investigated by many researchers due to their fundamental importance and practical applications.…”

We experimentally investigate the dynamics of surface waves excited by oscillations from a cylindrical sidewall. Particle-imaging-velocimetry measurements with fluorescent particles were used to determine the flow patterns near the sidewall of the cylindrical fluid container and to identify the locations of the evolving air–water interfaces. The high-frequency wall oscillations created four jets that originate at the cylindrical sidewall. Four vortex streets shed from the jets propagate from the sidewall to the centre of the container and subsequently excite a low-frequency gravity wave. The interaction between this gravitational surface wave and the high-frequency capillary waves was found to be responsible for creating droplet splash at the water surface. This phenomenon was first described as ‘Long-Xi’ or ‘dragon wash’ in ancient China. The physical processes for generating the droplet ejection, including the circular capillary waves, azimuthal waves, streaming jets and low-frequency gravity waves, are described in this paper.
