Research and application on numerical simulation of ship maneuvering motion under bank effect

Abstract

A ship maneuvering mathematical model was established considering the influence of river bank effect based on the depth integrated 2-D flow mathematical model. Tanking the section of the Suoluo beach reach of Lancang River in Yunnan Province as an example, the numerical simulation of ship maneuvering motion under bank effect was carried out. Results show that the typical ship can not ascend rapids when considering the bank effect, so it is necessary to implement channel regulation. The study reveals that the model can simulate the ship maneuvering motion and navigation status under bank effect, which can provide some useful references for the ship’s navigation and maneuvering in mountainous rivers.
