Study on the influence of the moonpool on the smooth water resistance performance of the ship
To investigate the influence of the flow pattern of the flow field on the resistance of a ship with a moonpool and the characteristics of the flow in the moonpool during smooth water navigation, the Star-CCM + software was used. The calculation results were verified by the experimental data of the pool, showing that the flow pattern of the moonpool has a great influence on the resistance performance of the ship with the moonpool. The force and the flow field of the moonpool have a great nonlinear change in the process from transition state to turbulence state. The flow in the moonpool also affects the forces on the hull. The main factors of the resistance of the moonpool and the fluctuation of the flow field are the constant shedding of the vortex street at the front of the moonpool, which causes the periodic change of the resistance of the moonpool and the phenomena of ‘piston’ and ‘sloshing’. The Reynolds number is the key similarity number that determines the characteristics of the moonpool flow field and determines the flow pattern and vortex shedding law.
