Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...

The European H2020 project SLOWD is aimed to investigate the fuel sloshing damping effect reduce design loads on aircraft wings. Wings house tanks and are highly flexible structures that can significantly deform under gust loads. In recent experiment by Martinez-Carrascal González-Gutiérrez [“Experimental study of liquid effects a SDOF vertical tank,” J. Fluids Struct. 100, 103172 (2021)], comp...

Chandra has significantly advanced our knowledge of the processes in the intracluster gas. The discovery of remarkably regular " cold fronts " , or contact discontinuities, in merging clusters showed that gas dynamic instabilities at the boundaries between the moving gases are often suppressed, most likely by specially structured magnetic fields. Cold fronts are not limited to mergers — Chandra...

Sloshing has many industry applications, namely in offshore engineering, aerospace, ship building, and manufacturing. simulation is essential to better understand the sloshing pattern consequently improve tank design reduce noise levels, stresses on structure, optimize baffle configurations arrangements. Thus, aim of this study determine effects perforated (porous) imperforate (solid) baffles p...

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 ...

Using the mosaic of six XMM-Newton observations, we study the hydrodynamic state of the A3562, a cluster in the center of the Shapley Supercluster. The X-ray image reveals a sharp surface brightness gradient within the core of A3562, a 200 kpc ridge extending to the south-west. A nearby group, SC1329313, imaged within this program also exhibits a tail aligned with the ridge. Study of the pressu...
