A spherical pendulum-type model was constructed to represent liquid sloshing in a cylindrical container caused by container transfer along a curved path. The model was used to design a curved path and a transfer control system in consideration of the damping of sloshing in the container. The curvature radius of the curved path and the acceleration of the container were determined using an input...

Fundamentals of nonlinear wave-particle interactions are studied in a Hele-Shaw configuration with wave breaking and a dynamic bed. To design this configuration, we determine, mathematically, the gap width which allows inertial flows to survive the viscous damping due to the side walls. Damped wave sloshing experiments compared with simulations confirm that width-averaged potential-flow models ...

Clearance of Thrust Vector Control (TVC) laws for launchers demands the capability to provide analytical certificates for the system’s robust stability. During exo-atmospheric flight, a key role is played by the ability to deal with non rigid-body effects such as fuel sloshing. Depending on its frequency and magnitude, sloshing can easily deteriorate the performance of the TVC laws to the point...

sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. in recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. on the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...

Nonlinear sloshing in an upright circular container near the lowest natural frequency is analyzed by using a fully nonlinear overset-mesh-based harmonic polynomial cell method, two weakly Narimanov–Moiseev-type multimodal models and linear method. Modal responses are extracted from results based on simple but accurate least-square procedure time series of free-surface wave elevations, which pro...

This is the first in a series of two papers aiming to establish sharp spectral asymptotics for Steklov type problems on planar domains with corners. In the present paper we focus on the two-dimensional sloshing problem, which is a mixed Steklov-Neumann boundary value problem describing small vertical oscillations of an ideal fluid in a container or in a canal with a uniform cross-section. We pr...

The transient coupling between the vessel motion and liquid sloshing in multiple tanks is investigated. External disturbance factors (e.g., spring constraint or force field) that might affect the oscillation characters of the coupling system are not involved so that the vessel motion is only excited by the liquid sloshing in tanks. The analytical solution for this coupling problem has been deri...
