Abstract:
Objectives The open area of the superstructure of a luxury cruise ship has a complex spatial layout and appearance modeling. In this study, the wind load and flow field characteristics in this area are accurately simulated to guide cruise ship design.
Methods The realizable k−ε turbulence model and substructure method in the Reynolds time-average method are used to numerically simulate the flow field characteristics of the whole cruise ship and the open area of the superstructure, and wind tunnel experiments are carried out for verification.
Results The appearance and spatial layout of the open area of the superstructure have an important impact on the flow field characteristics of the cruise ship, and the substructure simulation method can accurately simulate the flow field characteristics of the local area.
Conclusions When designing cruise ships, the overall shape of the superstructure should be streamlined and the height difference and spacing between adjacent structures in the open area should not be too large. The results of this study can provide guiding references for cruise ship design.
