REPRODUCTION OF SLOSHING PHENOMENA AND SLOSHING DAMPER DEVICE BY CFD

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2007
Sloshing phenomena of liquid in rectangular and circular tanks with and without sloshing damper have been simulated using a CFD method, namely a large eddy simulation method with standard Smagorinsky model. The decay of the wave amplitude in free oscillation, the resonance frequency and the amplitude response characteristics to a single-mode excitation

Prediction and Suppression of Liquid Propellant Sloshing-Induced Oscillation in RLV Terminal Flight

Aerospace
During the reentry terminal flight of lifting-body Reusable Launch Vehicles (RLVs) propelled by liquid fuel, the sloshing of liquid propellent presents new features that, if neglected, could lead to adverse flight oscillations or even worse.

Experimental Validation of Single- and Two-Phase Smoothed Particle Hydrodynamics on Sloshing in a Prismatic Tank

Journal of Marine Science and Engineering, 2019
This study aimed to validate the single-phase and two-phase smoothed particle hydrodynamics (SPH) on sloshing in a tank. There have been many studies on sloshing in tanks based on meshless particle methods, but few researchers have used a large number of

Study on sloshing simulation in the independent tank for an ice-breaking LNG carrier

International Journal of Naval Architecture and Ocean Engineering, 2020
As the LNG carrier operates in ice covered waters, it is key to ensure the overall safety, which is related to the coupling effect of ice-breaking process and internal liquid sloshing. This paper focuses on the sloshing simulation of the ice-breaking LNG

Effect of Double-Side Curved Baffle on Reducing Sloshing in Tanks under Surge and Pitch Excitations

Shock and Vibration, 2021
Sloshing is associated with the structural safety of liquid storage vessel. Installing the baffles inside the containers would be beneficial for the mitigating the damage due to the severe sloshing. In this study, an innovative type of double-side curved

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Fully non-linear simulation of second-order resonance in a three-dimensional tank using the PSME method [PDF]

, 2012
Sloshing occurs when a partially filled tank is subject to external excitation. If the excitation frequency is equal to half of the second-order natural frequency obtained from the linear theory, then second-order resonance may occur.

Experimental and numerical analysis of liquid sloshing within tank subjected to pitching motion

Applied Ocean Research
Liquid sloshing in partially filled tanks can generate large free surface oscillations, especially under pitch excitation. While extensive research has addressed sloshing in rigid containers, few studies focus on sloshing within flexible tanks or pure ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
