摘要：
A boundary element method for three-dimensional steady ship wave-making potentialproblems is established with the Rankine souree function as its fundamental solution.In the treatmentof the linearized free surface condition,one sided.upstream finite difference operator(FDO)is usedto suppress the upstream waves,and the equation of the disturbance velocity is established so that thefirst order FDO can be used in place of the second order FDO.Compared with the method with the sec-ond order FDO,the current method gives better precision and stability.Numerical examples are pre-sented for verification.
