Earthquake Sloshing in Annular and Cylindrical Tanks [PDF]

Journal of the Engineering Mechanics Division, 1979
The sloshing response of water in annular as well as in cylindrical tanks under horizontal earthquake ground motions is studied. A linear analysis, developed for the general annular tank problem, is based on potential flow theory. The predicted values of natural frequencies, surface displacements, and dynamic pressures are compared with measured data ...

On the Feasibility of Foundational Models for the Simulation of Physical Phenomena

International Journal for Numerical Methods in Engineering, Volume 126, Issue 6, 30 March 2025.
ABSTRACT We explore the feasibility of foundation models for the simulation of physical phenomena, with emphasis on continuum (solid and fluid) mechanics. Although so‐called “learned simulators” have shown some success when applied to specific tasks, it remains to be studied to what extent they can undergo severe changes in domain shape, boundary ...

A Calculation Method for the Sloshing Impact Pressure Imposed on the Roof of a Passive Water Storage Tank of AP1000

Science and Technology of Nuclear Installations, 2016
There is a large water storage tank installed at the top of containment of AP1000, which can supply the passive cooling. In the extreme condition, sloshing of the free surface in the tank may impact on the roof under long-period earthquake.

Effectiveness of Straight‐Wall and Sloped‐Wall House Hold Water Tank Acting as a Tuned Liquid Damper in Mitigating Structural Vibrations: A Dynamic Assessment

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This research distinguishes the performance of three types of water tanks, which are acting as tuned liquid dampers (TLDs; i.e., rectangular shape flat‐bottom with straight wall, square shape flat‐bottom with straight‐wall, and square shape flat‐bottom with sloped‐wall tanks) in the same plan area firmly fixed to the upper most part of the G+7 framed ...

An In‐Depth Analysis of Liquid Level Measurement Techniques and Performance Evaluation Using Computational Fluid Dynamics

Journal of Sensors, Volume 2025, Issue 1, 2025.
Liquid level measurement (LLM) systems are extensively used in industry. Although most liquid measurement systems are based on indirect measurement, flow‐based monitoring is the most used secondary measuring technique for LLM. A comprehensive review of the existing LLM techniques including optical, image‐based, capacitive, and float sensors is ...
