Experimental study of liquid slamming in elastic rectangular tanks under the flip-through impact
This paper considers the hydroelasticity effect in liquid slamming. A series of experiments were designed and performed in a nearly two-dimensional (2D) rectangular tanks with four elastic materials. The effect of the Young's modulus on the kinematic and dynamic characteristics of fluid-structure interaction (FSI) during flip-through impact is investigated. Furthermore, the peak values of slamming pressure, impact duration, pressure impulse and structural displacement in different cases are discussed. The hydrodynamic force of fluid acting on the sidewall is defined and compared for different cases. The results show that the Young's modulus of the sidewall plays an important role in hydroelasticity induced by liquid slamming. And a strong hydroelastic behavior could be observed when the impact occurs, especially in the case with a small Young's modulus. In addition, the artificial neural network (ANN) method is adopted to build the hydroelastic response prediction model. The relationship between Young's modulus and peak structural displacement is predicted with the model. This study could help verify and calibrate the theoretical and numerical models of the FSI problems in the sloshing tank and provide guidance on the study of hydroelastic slamming for the flexible cargo containment system.
