Internal solitary waves (ISWs) often seriously threaten the survivability of underwater submersible. Most existing investigations focus on interaction between ISWs and fixed or suspended submersibles. However, investigation self-propelled submersibles is still scarce, which a more realistic case in marine engineering. In this paper, three-dimensional numerical model for ISW submersible developed. Based extended Korteweg–de Vries (eKdV) theory, generated two-layer fluid wave tank by solving...
Floating structures are widely used in both shallow and deep waters industries such as offshore oil, gas, wind. However, the safety of floating subject to long-crested irregular waves is threatened by slowly varying wave drift forces. In this study, mesh-convergence laws for a panel model, which calculate second-order potentials using near-field approach, investigated semi-submersible platform an example. The effect relative-wave-height component low-frequency (LF) forces sensitive mesh near...
When the underwater submersible encounters an internal solitary wave (ISW), its loadings and motions are significantly disturbed. To investigate interaction mechanism between suspended ISW, a three-dimensional ISW–submersible-interaction numerical model was established, based on computational fluid dynamics (CFD) method. The generation propagation of ISW simulated in two-layer tank, according to eKdV theory. standard operation equation introduced simulate six degree freedom (6DoF) combined...

Internal solitary waves (ISWs) pose a significant threat to underwater submersibles. Unlike low-speed submersibles in the ISW field, high-speed form large pitching angle, which is more dangerous for submersible maneuverability. However, mechanisms behind interaction between ISWs and still remain unexplored. In this work, three-dimensional numerical model ISW–structure used investigate motion response characteristics of field. Based on extended Korteweg–de Vries (eKdV) theory, generated...
