Li, Q. and Hong, B.G., 2020. Numerical calculation of non-uniform flow field in water area at the end of a breakwater. In: Bai, X. and Zhou, H.

The control of ship motion in harbor water is a frontier problem in unmanned ship research. In harbor waters, affected by the shore type, the varied flow pattern has a great influence on ship motion. In this paper, numerical calculation method was used to study the influence of non-uniform flow on ship motion. a control-volume-based finite-difference scheme of the three-dimensional rectangular coordinate system was used for solving the two-phase transient Navier-Stokes equations. The dynamic process of water interaction with the ship and its (ship) free surface was investigated with the help of volume of fluid (VOF) technique. Moreover, the flow field and mechanical characteristics of the ship in the breakwater were analyzed under the action of cross flow. The force analysis of ship with respect to time and space such as the ship sailing out of breakwater with certain sail-angle and speed characteristics are also investigated. Finally, these numerical results were compared with that of experimental data which has a nice correlation with each other.
