摘　　要：A 3-D nonlinear,unsteady free surface problem of nearly vertical water entry of a disk-cylinder is investigated in this paper.By using a modified perturbation method and the Fourier cosine expansion method,the original 3-D nonlinear problem is reduced to a few of 2-D ones and then solved with the boundary integral equation method(BIEM).Numerical results are provided for the time dependent water surface and cavity surface as well as the pressure distribution on the bodv during its water entry.A 3-D nonlinear,unsteady free surface problem of nearly vertical water entry of a disk-cylinder is investigated in this paper.By using a modified perturbation method and the Fourier cosine expansion method,the original 3-D nonlinear problem is reduced to a few of 2-D ones and then solved with the boundary integral equation method(BIEM).Numerical results are provided for the time dependent water surface and cavity surface as well as the pressure distribution on the bodv during its water entry.
