A numerical research of nonlinear body-wave interactions (Q1195254)

This paper presents numerical research results on nonlinear body-wave interactions. The body-wave interaction is treated as a transient problem with known initial conditions. The development of the flow can be obtained by a time-stepping procedure, in which the velocity potential of the flow at any instant is obtained by utilizing a source density distribution on all boundary surfaces. The Orlanski's method [\textit{I. Orlanski}, J. Comput. Phys. 21, 251-269 (1976; Zbl 0403.76040)] is used to implement the boundary condition at the open boundary. The position of intersection points are determined by a direct method.
