They show clearly the separate and combined effects of compressibility and viscosity of water. They also have the advantage of being able to cover a wide range of excitation frequencies even beyond the cut-off frequencies of the natural modes of the reservoir. Key results obtained using the proposed analytical expressions of the hydrodynamic forces are validated using numerical and experimental solutions published for some particular cases available in the specialized literature.</p>}, number={2}, journal={Periodica Polytechnica Civil Engineering}, author={Tadjadit, Abdelmadjid and Tiliouine, Boualem}, year={2018}, pages={480–493} }
