Research on the influence of different hull crevasses on the outflow characteristics of water
Using impact dynamics simulation,various types of hull crevasses were constructed,and the hull crevasse shapes obtained by impact simulation were coupled into the constructed multiphase flow calculation model.The water out-flow characteristics of hull crevasses of different shapes,hull crevasses of different sizes,and hull crevasses of different flanging hulls;research shows that the outflow distance of the fracture shape with deeper flanging tear is farther.The out-flow distance is smaller at first and then larger than the inner flanging crevasse.Compared with the 400 mm,300 mm and 200 mm crevasses,the outflow distances at the same time are slightly different,but the stable value of the impact pressure is quite different.The 400 mm crevasse is 34 700 Pa,1300 Pa larger than the 300 mm crevasse and 5 700 Pa larger than the 200 mm crevasse.The research can provide accurate data support for the plugging and sealing operation after the hull is dam-aged,and can also provide technical guidance for the design of new plugging equipment.
