We report laboratory measurements of the parallel current carried by suprathermal electrons associated with inertial Alfvén wave excitation in the laboratory. The experiments presented here use a novel wave absorption diagnostic that measures the suprathermal tails of the electron distribution parallel to the mean magnetic field. The diagnostic is used to probe the electron distribution as an i...

Motivated by recent experiments on the hovering of passive bodies, we demonstrate how a simple shape-changing body can hover or ascend in an oscillating background flow. We study this ratcheting effect through numerical simulations of the two-dimensional Navier–Stokes equations at intermediate Reynolds number. This effect could describe a viable means of locomotion or transport in such environm...

This paper proposes a design method of a damping path for a cylindrical liquid container transferred with a wheeled mobile robot. The damping path is constructed from the acceleration using the principle of an input shaping method. Although a positional error is occurred by using the input shaping method, it is easy to correct the error with the proposed method. The proposed design method can b...

Low-capillary number or surface tension dominated flows are found in a number applications, ranging from small scale microfluidics up to larger scale analysis of microgravity sloshing. This paper evaluates the possibility of modelling of surface tension dominated multiphase flows using an Eulerian volume-of-fluid (VOF) approach with high-resolution surface capturing. With the aim of improved st...

Resonant sloshing in circular cylinders was studied by Faltinsen et al. (2016), whose theory used to describe steady-state resonant waves due time-harmonic container's elliptic orbits. In the limit of longitudinal container motions, a symmetry-breaking planar wave solution occurs, with clockwise and anti-clockwise swirling equally likely. addition this primary harmonic dynamics, previous experi...

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...
