“…Since the earthquakes are unpreventable and unpredictable the only course open to the engineers is to design and built the fluid-structure system so that the loss of property and life can be minimized. For ground excitation dominated by low-frequency contents, the sloshing response increases significantly and the contribution of the higher sloshing modes increases [34,35]. Since the pioneering works of Dodge et al [1], Miles [21], Bauer [23], Abramson [26] and Housner [27], many research groups have concentrated their investigations on the seismic behaviour of the liquid containers and on the earthquake resistant design to understand the dynamic behaviour of the liquid storage tanks and to provide proper design codes.…”

SUMMARYThis paper brings into focus some of the interesting effects arising from the motion of the liquid free surface due to sloshing in partially filled containers of several geometrical shapes in two dimensions. The slosh characteristics that include frequencies, free surface profiles and the hydrodynamic pressure over the container walls have been reported in this study. The equations of motion of the fluid, considered inviscid, are expressed in terms of the pressure variable alone. It is assumed that the frequency of the exciting oscillation is not in the immediate neighborhood of the natural slosh frequency, so that the slope of the free surface is small. Simple harmonic oscillation and earthquake excitations are used as the prescribed boundary conditions. A finite difference-based iterative time-stepping technique is employed to advance the solution in the time domain. The paper presents numerical solutions for rectangular, vertically mounted annular cylindrical, trapezoidal and horizontal circular cylindrical containers. Numerical results obtained are compared with the available existing solutions to validate the code developed. The parametric study of the slosh dynamic systems shows the importance of the nature of excitation, fluid height and the geometry of the container.

“…Many researchers have studied this phenomenon in the past few decades to estimate liquid free surface or pressure in different storage tank geometric shapes. Choun and Yun [1], Chen and Chiang [2], Celebi and Akyildiz [3], Frandsen [4], Akyildiz and Unal [5,6], Chen and Nokes [7], Wu [8], Lee et al [9,10], Liu and Lin [11], Panigrahy et al [12], Belakroum et al [13], Ming and Duan [14], Huang et al [15], Jung et al [16] and Pirker et al [17] studied the sloshing phenomenon in rectangular tanks. Wu [8] studied probability of exciting second-order resonance in a rectangular tank in horizontal motion and its relation to natural frequencies of the tank.…”

“…Williams and Moubayed [9] calculated hydrodynamic pressure on rigid tank walls by boundary integral method due to horizontal and vertical excitations considering fluid to be linearly compressible. The effects of a bottom-mounted rectangular block on the sloshing characteristics of the fluid in rectangular tanks were investigated by Choun and Yun [10] using the linear water wave theory. The hydrodynamic pressure exerted on the tank wall and on the mounted block is changed significantly as the block becomes large and moves toward the wall.…”
