This paper presents a model based experimental investigation to demonstrate the usefulness of an active damping strategy to manage fluid sloshing motion in spacecraft tanks. The active damping strategy is designed to reduce the degrading impact on maneuvering and pointing performance via a force feedback strategy. Many problems have been encountered until now, such as instability of the closed ...

In this study, the liquid sloshing in a cylindrical tank considering soil–structure interaction and undergoing horizontal excitation is investigated analytically. Multiple rigid annular baffles are positioned on wall to mitigate sloshing. Firstly, combined with subdomain partition method for sloshing, complex domain partitioned into simple subdomains single condition boundary. Based continuity ...

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...

A quantitative comparison of the usual and recent numerical treatments which are applied to the Smoothed Particle Hydrodynamics (SPH) method are presented together with a new free-surface treatment. A series of numerical treatments are studied to refine the numerical procedures of the SPH method particularly for violent flows with a free surface. Two dimensional dam-break and sway-sloshing prob...

To ensure that a liquid tank semi-trailer has good yaw stability and path-following performance on low-adhesion roads under turning conditions, multi-object PID differential braking-control method is proposed, which takes the tractor rate, articulation angle as control parameters. According to principle of equivalence, trammel pendulum (TP) model used simulate sloshing effect in tank, Fluent so...

The stress at the support structure of clarification tank is large, which will have a certain impact on whole structure. typical concentration phenomenon cause structural damage and serious harm to steel itself. In order study influence bearing plate seismic response tank, this paper analyzes dynamic by setting different thickness plates connection between column body tank. Based displacement, ...

Partially filled liquid-carrying tanks have been used in many engineering applications, such as ships, vehicle fuel tanks, rockets, and drink or petroleum tankers. Liquid sloshing is an exciting phenomenon that researchers are investigating because of its complex behavior specifications. In this study, the responses a prismatic tank with approximate volume automobile under different laterally h...

Abstract In this paper, a nonlinear reduced-order model based on neural networks is introduced in order to vertical sloshing presence of Rayleigh–Taylor instability the free surface for use fluid–structure interaction simulations. A box partially filled with water, representative wing tank, first set harmonic motion via controlled electrodynamic shaker. Accelerometers and load cells at interfac...

the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

Abstract The stratified LNG is the potential cause of rollover, so analysis interface behavior very important. In this work, a three-layer dynamic simulation model BOG, LNG, and liquid nitrogen sloshing in tank was built. transient behaviors layers were simulated, effects factors such as period (T = 0.2, 0.4, 0.6, 0.8 1.0 s) amplitude (A=0.01~0.06 rad) analyzed. It found that instability aggrav...
