Abstract Fuel sloshing-induced damping is currently being studied extensively within the EU-funded SLOWD project as a means of passively reducing dynamic loads in aircraft wings. It interest to be able determine which parameters have greatest influence on added from sloshing motion. An uncertainty measured force has been observed when multiple consecutive and identical oscillation cycles are co...

Conventional liquefied natural gas (LNG) cargo vessels are imposed with tank-fill limitations as precautions to prevent structural damage and stability-loss due high-impact sloshing, enforcing volume-fills be lower than 10% or higher 70% of the tank height. The restrictions, however, limit commercial operations, specifically when handling spot trades offshore loading/unloading at multiple ports...

Shallow water sloshing-structure interaction under the coupled longitudinal and pitch motions resulted by earthquake directly affects structural safety of shiplift. However, no matter in shiplift or other related fields, there is little research on this aspect at present. As a basis dynamics analysis resistant design, an analytical method including developed modal system new engineering formula...

Abstract. The subject of study is the influence of sloshing liquid on board spacecraft and satellites. Experiments have been carried out with the mini satellite Sloshsat FLEVO, containing a partially filled water tank, in an orbit around earth. These experiments were supported by a computational model for 3D incompressible free-surface flow, including capillary surface physics and coupled solid...

We treat the noise-activated escape from a one-dimensional potential well of an overdamped particle, to which a periodic force of fixed frequency is applied. Near the well top, the relevant length scales and the boundary layer structure are determined. We show how behavior near the well top generalizes the behavior determined by Kramers, in the case without forcing. Our analysis includes the ca...

Suspending a rectangular vessel partially filled with an inviscid fluid from a single rigid pivoting rod produces an interesting physical model for investigating the dynamic coupling between the fluid and vessel motion. The fluid motion is governed by the Euler equations relative to the moving frame of the vessel, and the vessel motion is given by a modified forced pendulum equation. The fully ...
