EFFECTS OF WATER DEPTH ON STOPPING MANEUVER USING CFD NUMERICAL SIMULATION
As the increasingly-crowded ports and waterways,stopping ability is critical to the safety of ship maneuvering.When a ship travels in shallow water,maritime disasters such as collision and grounding occur more easily than in open waters.Therefore,it is necessary to study the behaviour of large marine vehicles in shallow water.In this paper,naoe-FOAM-SJTU solver with a hierarchy of bodies like hull,propeller and rudder using overset grid technology based on open source CFD platform OpenFOAM developed by Wan Dechengs research team in Shanghai Jiao Tong University is used to numerically investigate complex ship motion problem in stopping manuever.The simulation starts from the steady state of self-propulsion.Then the propeller is controlled to a reverse speed to carry on the stopping manuever,both in shallow and deep water.Detail information such as longitudinal and lateral distance,ship velocity and other relative parameters during stopping manuever are presented.Shallow water effects on stopping manuever is analysed through comparison of trajectory,forces,pressure distribution and flow field situation.In conclusion,several suggestions are provided to the choice of safe stopping methods in shallow water.
