Study of liquid sloshing: numerical and experimental approach

Abstract

In this paper, sloshing phenomenon in a rectangular tank under a sway excitation is studied numerically and experimentally. Although considerable advances have occurred in the development of numerical and experimental techniques for studying liquid sloshing, discrepancies exist between these techniques, particularly in predicting time history of impact pressure. The aim of this paper is to study the sloshing phenomenon experimentally and numerically using the Smoothed Particle Hydrodynamics method. The algorithm is enhanced for accurately calculating impact load in sloshing flow. Experiments were conducted on a 1 : 30 scaled two-dimensional tank, undergoing translational motion along its longitudinal axis. Two different sloshing flows corresponding to the ratio of exciting frequency to natural frequency were studied. The numerical and experimental results are compared for both global and local parameters and show very good agreement.

Numerical Modeling and Experimental Validation of Free Surface Flow Problems

“…Many versions of such problems have been analyzed by other authors to validate their numerical formulations. As examples (not exhaustive), sloshing problems has been studied in [4,21,60,68,78,107,120,134,174,194,213,226]. Particularly, in [65], Lagrangian type techniques are applied, and moderate to large amplitudes are analyzed and primary resonance response is described.…”

Numerical Analysis of Liquid Sloshing Using the Incompressible Smoothed Particle Hydrodynamics Method

“…Although the temporal variations in water height with both pressure boundary conditions are generally comparable with the experimental values, the peak wave height values in case C2, even at The maximum water height from case C1 is a better fit to experimental data. Figure 5 presents snapshots of the pressure distributions for a liquid sloshing model in a rectangular tank (shown in Figure 1(b)) which corresponds to the experimental work of Rafiee et al [35]. The low filling depth ( = 0.2 ) and greater longitudinal tank motion ( = 0.1 m) at the resonance frequency, evidently lead to different sloshing behavior compared to in the first model (refer to Figure 3).…”

“…Thus, sloshing was induced by an excitation motion, = (1 − cos ), where the amplitude, , is 0.005 m, and the excitation frequency is = 0 . The second model was constructed based on the experimental work of Rafiee et al [35], with a low ratio of filling depth ( = 0.2 ) and an excitation of sinusoidal motion, = sin . Here, the large amplitude of the motion ( = 0.1 m) and resonance frequency, = 3.116 rad/s, were applied.…”

“…The comparison of impact pressures at points P119 and P136 between the present incompressible SPH method (with Neumann pressure boundary condition, C1) and the experimental results [35] is presented in Figure 6. It is clear that numerical results are in good agreement with experimental data.…”

Modeling of thermomechanical properties of polymeric hybrid nanocomposites

“…Most recently, Rafiee and Ghorbanhosseini [32] developed a systematic computational modeling in the form of hierarchical process to predict the mechanical properties of FFC. The same authors [33] developed stochastic multiscale modeling for predicting the mechanical properties of fuzzy fiber coated with randomly oriented CNTs.…”
