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

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 ...

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.

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 ...

Never Mind the Bollards: Exploring the Role of GCHQ, MI5, and the National Technical Authorities in UK Security Markets

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT The cultures and governance of security markets in the United Kingdom are often characterised through a paradoxical narrative of simultaneous state retreat and progressive advance. In the face of repeated recent high‐profile security failures, and global changes in material political economy, we argue that UK security governance is adapting to

Effects of boundary layer and liquid viscosity and compressible air on sloshing characteristics

International Journal of Naval Architecture and Ocean Engineering, 2015
In this paper, numerical investigations for tank sloshing, based on commercial CFD package FLUENT, are performed to study effects of boundary layer grid, liquid viscosity and compressible air on sloshing pressure, wave height and rising time of impact ...

Comparison of finite and boundary element methods in problems of oscillations of a composite shell of revolution with a liquid

Вісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2019
The phenomenon of sloshing can be described as the movement of the free surface of a liquid contained in a reservoir under the action of a suddenly applied load.

Numerical analysis on the sloshing of free oil liquid surface under the variable conditions of vehicle

Advances in Mechanical Engineering, 2019
Oil liquid sloshing is the sloshing of free oil liquid surface in the fuel tank filled partially. The variable conditions of vehicle mainly include braking, acceleration, and deceleration. It is verified that the simulation method is reliable by the test.

A Practical Guide to First‐Principles Calculations for Pseudocapacitive Materials: From Electrochemical Experiments to Atomistic Understanding

ChemElectroChem, Volume 13, Issue 20, 16 October 2026.
Electrochemical experiments reveal what happens, whereas first principles calculations explain why. Emerging computational electrochemistry is bridging these perspectives, enabling quantitative understanding of electrode/electrolyte interfaces and enabling the rational design of next‐generation energy storage materials.
