| Abstract: | The three-dimensional model of an underwater explosion bubble near a surface ship is described.The boundary integral method is used to solve Laplace equation based on potential-flow theory.Studies are carried out to simulate the bubble motion,with emphasis on the loading of the ship hull.The results demonstrate the destructive effect of the ship hull subject to the explosion bubble. |
