“…Park et al carried out the dynamic test of the cylindrical liquid-containing tank under horizontal seismic action and determined the occurrence of the beam and elliptical vibration modes according to the acceleration results measured at different positions [ 22 ]. Kotrasova and Kormanikova investigated the influence of liquid on the tank when the liquid-containing structure was subjected to horizontal acceleration [ 23 ]. Hydrodynamic pressure, including impulsive pressure and convective pressure, was excited, and the seismic responses of multiple sizes of circular liquid-containing structures fixed on a rigid basis were calculated.…”

The research object is the ground-rested circular RC tank. The innovation is to reveal the hydrodynamic pressure law of ground-rested circular RC tanks under bi-directional horizontal seismic action. The relationship between the sloshing wave height and hydrodynamic pressure is determined, the hydrodynamic pressure components and their combination are verified, calculation methods for hydrodynamic pressure are developed, and their distribution laws are presented. The results show that convective hydrodynamic pressure cannot be ignored when the tank is subjected to seismic action. Hydrodynamic pressure under unidirectional horizontal seismic action in X or Y direction is obtained by square root of the sum of impulsive pressure squared and convective pressure squared. Total hydrodynamic pressure under bi-directional horizontal seismic action is obtained by the square root of the sum of X-direction hydrodynamic pressure squared and Y-direction hydrodynamic pressure squared. This method can ensure the accuracy and reliability of hydrodynamic pressure calculation.

“…The knowledge of hydrodynamic effect of fluid on liquid storage tanks during the movement of the earth surface contributes to reliability and earthquake resistance of liquid-containing or liquid-transporting systems [11]. The design of containers loaded of earthquake is encouraged by various codes [3] IBC 2000, ACI codes, AWWA codes, API, Eurocode 8, NZSEE and Indian code. In this paper will be analyzed seismic response of rectangular infinitely long tank -canal by using of Eurocode 8 [4] and Indian standards [5] by simulating of Finite Element Method (FEM) with comparing of numerical solution using of FEM the Arbitrary-Lagrangian-Eulerian (ALE) formulation with the two way Fluid-Structure Interaction (FSI) techniques for simulation of the interaction between the structure and the fluid at the common boundary [6].…”

The dynamic behavior of fluid filling in moving containers is a phenomenon that has attracted the attention lot of scientists. The liquid in an arbitrary shaped container under external excitations exerts the hydrodynamic pressure that with hydrostatic pressure acting together onto walls and bottom of container. The knowledge of the hydrodynamic fluid response on the solid domain of structure contributes to reliability and earthquake resistance of liquid-containing systems. This paper presents the possibility of simulation endlessly long fluid filled the rectangular tank -channel due to an action of horizontal ground motion. The Finite Element Method was used for simulation of this problem. One computational model uses FEM formulation ALE FSI and two models simulate only the solid domain by FEM and fluid effect due to horizontal ground motion is simulated by fluid-quasistatic hydrodynamic pressure given by Eurocode 8 and Indian standard.

“…Flow around a cylindrical object is one of the frequently solved problems; the simple geometry of the cylinder is an interesting physical phenomenon. It concerns various types of structures such as cooling towers, chimneys [3], buildings of circular shape (Figure 1), pylons for cable cars, bridge structures [4][5][6], offshore structures, air-cooled heat exchanges [7], storage tanks, and other industrial buildings [8] and their structural components. More detailed knowledge of the flow field and the effects of wind flow on objects finds its application not only in civil engineering [9], but also in wind engineering [10].…”

Modeling the wind flow around cylindrical buildings is one of the problems within urban physics. Despite the simple geometry of the cylinder, it is an interesting physical phenomenon. Partial knowledge of flow field properties can be found in the literature, but in terms of their use for practical tasks, the data are still incomplete. The authors performed a numerical analysis of the flow around the smooth cylinder in the subcritical and critical regime for Reynolds numbers in the range of Re = 2.3 × 103 to 4 × 105. Turbulent flow was solved using LES model and the numerical solution was compared with available data from experiments or standard. Analysis of the mean stream velocity showed the elongation of the core of the wake with decreasing Re. The pressure coefficient evaluation showed a big difference between its distribution in the subcritical and critical regime. In the subcritical regime, a significant increase in the minimum value and a shift of the extreme close to the axis of the cylinder is proven. The results of the drag coefficient confirm a significant decrease in the transition from subcritical to critical regime, which is indicated in the cited experiments.
