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...

Abstract Sloshing describes liquids motion in the semi-filled tanks, and exerts dynamic loading on its walls. This effect is of great importance in a number of dynamic systems e.g. aerospace vehicles, road tankers, liquefied natural gas carriers, elevated water towers and petroleum cylindrical tanks. Pressures insert impacts which are important for structural strength evaluation and its co...

Construction and assembling process of shell structures has caused main problems. In these structures, there is no possibility for the integrated construction due to their large shell extent and they are built using a number of welded curved panel parts; hence, some geometrical imperfections emerge. Most of these imperfections are caused by the process of welding, transportation, inappropriate ...

Experiments were conducted to study the performance of circular and square tank surface aerators on the oxygen transfer coefficient and to a limited extent on power requirements. All the tanks are geometrically similar except for their shapes. They consist of a rotor of diameter, D, fixed with six flat blades rotating with a speed, N, in pure waters of viscosity, υ, at room temperature. A simul...

Abstract Some corrosion progress trends specific for cylindrical steel shells of typical above-ground fuel tanks are first identified experimentally and then quantitatively compared with one another. The inference is based on many random thickness measurements related to the selected corrosively weakened coating sheets carried out at various moments in question service time. It shown detail tha...
