regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing every day. thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important. in this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. to ease of efficient design, theses parameters ...

In this paper, a one-port time-domain/frequencydomain based technique using a short-circuited coaxial geometry inserted vertically in a liquid tank is designed and presented as a multi-level storage tank gauge and monitor. For storage tanks of small physical liquid levels, the attenuation inside the coaxial cable sensor may be neglected and both the physical liquid levels and liquid permittivit...

Previous composite cryotank designs have relied on the use of conventional composite materials to reduce microcracking and permeability. However, revolutionary advances in nanotechnology derived materials may enable the production of ultra-lightweight cryotanks with significantly enhanced durability and damage tolerance, as well as reduced propellant permeability. Layered silicate nanocomposite...

A recently developed EITS system, the UCLH mk2.5 was tested on a resistor phantom and in linear time and frequency difference imaging of a cylindrical tank, 10cm diameter, filled with 0.1% saline, and 16 electrodes in a ring; the test object was a cylinder of banana, 2 cm long and 1 cm in diameter. Reproducible images with the same location as the test object were obtained with both methods. No...

Sloshing is an important issue for LNG tanks and in general when partially filled tanks are on-board of a vessel. This resonance phenomenon may be connected with complex motions of the filled liquid that can couple with the ship motions and can represent a danger for the tank strucure and for the stability of the ship. In this context, it is very important to identify the possible scenarios ass...

In the present work damping effect of sloshing flows in tanks subjected to vertical harmonic oscillations is modelled through Smoothed Particle Hydrodynamics (SPH) numerical method. The prediction energy dissipation these problems interest, among others, aeronautic field appropriately address sloshing-induced loads on aircraft wings. To this purpose, an enhanced SPH scheme applied and extensive...
