FEM simulation of the endlessly long fluid filled canal due to horizontal ground motion

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.
