125744 - Investigation of Sloshing Loads Considering Dynamics of Liquid Storage Tanks Using Smoothed Particle Hydrodynamics 

The fluid flow partially filled in liquid storage tanks is referred to as sloshing flow. It is an important issue in various engineering fields such as oil and liquified gas transportation. Generally, the motion of the internal flow is generated by the external excitations of the tanks and 'it is widely recognized that the internal flow impacts the wall of the tank periodically which induces the hydrodynamics loads acting on the tanks. This phenomenon can cause structural damage and instability of dynamic systems. Therefore, it is necessary to investigate the sloshing loads acting on the tanks, considering various patterns of tank movement. In this paper, smoothed particle hydrodynamics (SPH), a widely used meshless particle method, is used. Due to its attractive features, the analysis of sloshing flow including violent free surfaces can be easily conducted without additional complex numerical treatments. Through the various numerical examples, the patterns of free surface flow and hydrodynamic loads acting on the tanks are investigated in detail, considering the dynamic conditions of the tank such as sharp turns, accelerated movement, and sudden stops. Additionally, the effects of baffles installed in the tank are investigated, especially focused on the reduction of hydrodynamic loads. To demonstrate the performance of the proposed methodologies, various numerical tests are conducted considering rectangular and cylindrical tanks. This result can contribute to evaluating the safety evaluations of tank designs and transport operations.
