Vibration absorbers are employed for both structural safety and comfort reasons. This paper explores a novel absorber which uses the sloshing of granular particles to dissipate energy in a rolling container. Some of the parameters which affect energy dissipation have been experimentally studied. Detailed description of one experiment is given. Further work involves numerical exploration.

The present paper introduces the sloshing effects on aeroelastic stability and response of flying wing configurations. Using reduced order model based data provided by computational fluid dynamics data, description slosh is introduced into an integrated modelling that accounts for both rigid elastic behaviour flexible aircraft. fully unsteady aerodynamics, modelled in frequency domain via doubl...

This paper presents a computational study of the fluid-structure interaction (FSI) mechanism in pressurized commodity tank cars in railroad application. Within the Lagrangian framework of Abaqus/Explicit, finite element analysis (FEA) is conducted to predict the structural response of tank cars under dynamic impact loading. A three-phase approach is adopted that explicitly models pressurized ga...

We present a method for charge mixing in self-consistent density functional calculations which uses the Thomas-Fermi-von Weizsäcker equation to solve implicitly for the charge density response function to the potential. This approach has significant improvements over existing methods, particularly for inhomogeneous systems with large unit cells which commonly suffer from poor convergence due to...

Oscillating water column wave energy converter is a power generation device in which ocean waves excite the oscillation of surface an air chamber, generates fluctuations pressure and rotate turbine generator(s). The fluid chamber phenomenon with natural period, similar to container such as sloshing. Previous research has shown that for oscillating single submerged water, characteristics can be ...

This paper presents an investigation of sloshing loads acting on liquid cargo tanks based classification rules and numerical simulations. For the design tanks, load is one key factors that should be considered. To reduce motion contained liquid, internal structures such as bulkheads baffles are commonly installed in tanks. In rules, methodologies to estimate proposed considering parameters rela...
