Numerical Analysis of Propeller-Induced Hydrodynamic Interaction between Ships

The hydrodynamic interaction effects between ships are significantly pronounced in restricted waters, and this may potentially threaten the safety of ships, especially given that ship dimensions waterway traffic have kept increasing. Although there has been a good amount research on interactions, study effect propeller ship’s is very limited. In paper, series RANSE-based numerical simulations carried out to characteristics near-field without speed. forces moment acting calculated analyzed. Through analysis flow field behavioral pattern forces, it found significant influence pressure distribution hull as well forces. maximum lateral force interacting could reach 0.58 times standard thrust KP458 (the revolution 594 rpm velocity coefficient 0.25 open water).
