... incoming periodic waves (Huseby and Grue, 2000; Kristiansen and Faltinsen, 2017). The primary focus of the theoretical studies have been to capture the components of the wave force up to the third harmonic wave frequency (Faltinsen et al., 1995; Malsenica and Molin, 1995). Some fully nonlinear potential...

... proposed to increase the inherent damping of the sloshing tank. It has been found that perforated plates can efficiently dissipate the energy of sloshing meanwhile improve the stability of the tank system (Tait et al., 2005; Faltinsen and Timokha, 2001). Recently, Jin et al. (2014) showed in experimental...
