cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. usually failure of cylindrical tanks leads to serious consequences. during the past earthquakes such as 1964 alaska and 1999 turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. therefore, evaluation of seismic performance of these str...
A thorough understanding of the effects sloshing on aircraft dynamic loads is great relevance for future design flexible to be able reduce their structural mass and environmental impact. Indeed, high vertical accelerations caused by vibrations structure can lead fragmentation fuel free surface. Fluid impacts tank ceiling are potentially a new source damping that has hardly been considered befor...
The boundary-value problem for the linear horizontally-forced sloshing problem can be solved using two different classes of eigenfunction expansions. The first will be referred to as the ”cosine” expansion since the organizing centre is a cosine series in the x−direction (the horizontal direction), and the second is called the “vertical eigenfunction expansion” since the organizing centre is a ...
This paper describes a novel numerical model aiming at solving moving-boundary problems such as free-surface flows or fluid-structure interaction. This model uses a moving-grid technique to solve the Navier–Stokes equations expressed in the arbitrary Lagrangian-Eulerian kinematics. The discretization in space is based on the spectral element method. The coupling of the fluid equations and the m...
The present study is to carry out a numerical sloshing using smoothed particle hydrodynamics (SPH) in the prismatic tank. Sloshing violent flow caused by resonance of fluid tank external oscillation. was used resemble membrane LNG type carrier. experiment carried three pressure sensors, camera high resolution, and four degrees freedom forced oscillation machine. In this study, filling ratio 25%...
Sensitivity of gravitational-wave detectors is limited in the high-frequency band by quantum shot noise and eventually optical loss signal recycling cavity. This limit main obstacle on way to detect gravitational waves from binary neutron star mergers current future generation detectors, as it does not depend either arm length, or injected squeezing level. In this paper, we come up with sloshin...
