Study on Sloshing Characteristics in a Liquid Cargo Tank under Combination Excitation

Sloshing is a common flow phenomenon in liquid cargo tanks and has great negative impact on the stability safety of ship navigation. It important to understand sloshing process under excitation complex external conditions for transportation cargo. In this paper, characteristics tank are studied combination roll surge. The pressure distribution at different positions discussed, along with influence tank. results show that condition excitation, fluid sloshes diagonal direction tank, peak height located corner lowest point proportional amplitude angle surge, change significant positions.
