Tanks, as instruments in oil and its product’s amount measurement system chain, must be regularly maintained metrologically inspected, they significantly contribute to uncertainty. However, when measuring a change the of stored material (i.e., transfer), uncertainty becomes highly dependent not only on mass transaction but also initial liquid level tank. This paper provides modeling uncertainti...

Abstract This paper presents the buckling response and vibration characteristic of cylindrical steel liquid storage tanks filled with water when subjected to strong earthquake excitations. Finite element analysis (FEA) is performed by using ABAQUS software. The geometrically perfect different R/t H/R ratios are considered for modal linear seismic analysis. modeling method, appropriate type, nec...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

The article describes the actual work’s numerical analysis for unit joining walls to bottom of vertical cylindrical tank 50 thousand m 3 . Having analyzed relevant stress-strain state tanks different types finite element model. Research carried out with a wall on rigid base. Features should include effect various loads: static, dynamic, cyclic, corresponding normal operation. load pressure liqu...

A highly optimized simulated annealing (SA) algorithm is applied to reconstruct permittivity images of real two-phase gasoil flows through a cylindrical vessel using electrical capacitance tomography (ECT). ECT yields low-accuracy images but is robust, inexpensive and much faster than many other tomography processes. This non-intrusive method essentially measures nonconductive system distributi...
