Abstract

The Blind Test Series of ISOPE-2025 with simulation of isothermal sloshing in a circular tank have been conducted by a virtual boundary force (VBF) codes NEWTANK which is a robust software solving NStype equations by finite difference method using VOF method to track free surface, combining non-inertial coordinates to simulate fluid sloshing. In the study, fluid sloshing with forced harmonic horizontal excitation is simulated and compared with experimental data obtained from the COAST Laboratory, the University of Plymouth, UK firstly. Then fluid sloshing with forced harmonic vertical excitation is simulated. The circular tank size and simulation status are the same as experimental settings. The numerical results are analyzed and compared with experimental data.
