| Abstract: | A reciprocal theorem of dynamics for potential flow problems is first derived by means of the Laplace transform in which the compressibility of water is taken into account.Based on this the- orem,the corresponding time-space boundary integral equation is obtained.Then,a set of time do- main boundary element equations with recurrence form is immediately formulated through discretiza- tion in both time and boundary.After having carried out the numerical calculation two solutions are found in which a rigid semicircular cylinder and a rigid wedge with infinite length suffer normal impact on the surface of a half-space fluid.The results show that the present method is more efficient than the previous ones. |
