CFD-based simulation of cruise ship damage and immersion
Ship damage and flooding have always been a key issue of extensive concern and continuous research in the shipbuilding industry.The damage stability of ships is particularly important for the survivability of ships after flooding.Cruise ships are important members of large passenger ships.Therefore,in this paper uses the method of computational fluid dynamics to study a cruise ship,and the fluid calculation software used is STAR-CCM+.Single-chamber flooding and multi-chamber flooding were carried out in still water environment.The results show that for such a large passenger ship as a cruise ship,flooding of a single chamber has little effect on the stability of the cruise ship.The flooding water of the cham-ber is more obvious in the lateral movement.In the early stage of multi-chamber flooding,the movement of the cruise ship changes slowly,and the inclination angle increases sharply in the later stage,which is very prone to capsizing.With the re-ciprocating movement of the submerged chambers,the cruise ship is also threatened to break from the middle.
