The double-row and double-chamfered aquaculture tank is a special structure of the ship. sloshing this coupled with hull motion, which has an important impact on safety motion. In present study, research motion response ships was conducted based model seakeeping tests in regular waves. test results were compared numerical simulation solid loading without sloshing. showed that pitch consistent a...
Sloshing is an important issue for LNG tanks and in general when partially filled tanks are on-board of a vessel. This resonance phenomenon may be connected with complex motions of the filled liquid that can couple with the ship motions and can represent a danger for the tank strucure and for the stability of the ship. In this context, it is very important to identify the possible scenarios ass...
Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in the past several decades. Most reported studies have been for tanks excited by forcing motion in a limited number of directions and with fixed excitation frequencies throughout the forcing. In the present study, a time-independent finite difference method is used to simulate fluid sloshing in the t...
Trapped modes in the linearised water-wave problem are free oscillations of an unbounded fluid with a free surface that have finite energy. It is known that such modes may be supported by particular fixed structures, and also by certain freely-floating structures in which case there is, in general, a coupled motion of the fluid and structure; these two types of mode are referred to respectively...
A modified moving particle semi-implicit (MPS) method based on GPU acceleration technique is applied to simulate three-dimensional (3-D) free surface flow by using our in-house solver MPSGPU-SJTU in this work. In order to validate MPSGPU-SJTU solver, 3-D dam break and sloshing, two typical violent flows with large deformation and nonlinear fragmentation of free surface are simulated. For dam br...
The coalescence of magnetic islands in the low-resistivity eta, Hall-MHD regime is studied. The interaction between the ion inertial length d(i) and the dynamically evolving current sheet scale length deltaJ is established. Initially, d(i) << deltaJ. If eta is such that deltaJ dynamically thins down to d(i) prior to the well-known sloshing phenomena, then sloshing is avoided. This results in et...
The motion of fluids within partially filled containers has been the subject of much study by scientists and engineers due, in large part, to its importance in many practical applications. For example, civil engineers and seismologists have actively studied the effects of earthquake-induced fluid motions on oil tanks and water towers. In recent years, aerospace engineers have been concerned wit...
This paper presents ExxonMobil’s evolution of a direct sloshing assessment methodology to resolve several challenging technical issues that are essential for evaluating the integrity of LNG containment systems. Among the most significant developments is the introduction of a probabilistic-based framework that facilitates modeling of the high variability of sloshing impact pressures due to slosh...
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...
