Comprehensive Study on Sloshing Impacts for an Offshore 3D Vessel via the Integration of Computational Fluid Dynamics Simulation, Experimental Unit, and Artificial Neural Network Prediction
Liquid sloshing in vessels subjected to forced acceleration could lead to dangerous operating and safety issues for aerospace vehicles, large dams, oil tankers, marine vessels, storage tanks, and so forth. In this paper, a comprehensive study to characterize the sloshing phenomenon for an offshore 3D vessel has been performed. The study integrates the computational fluid dynamics for rigorous sloshing simulations, the setup and measurement for a pilot-scale experimental testbed for simulation validation, as well as the employment of an artificial neural network method for effective sloshing impact prediction. Based on this comprehensive study, the sloshing impacts such as the maximum height of the free surface, the average cross-sectional pressure, and the maximum forces on the vessel wall have been systematically studied under various parameter changes of liquid filling level, frequency of the imposed waves, and amplitudes of different sea-state conditions. This study demonstrates its efficacy in characterizing and predicting general sloshing impacts, which would be helpful for future industrial applications.
