✦ Synopsis
In this paper the numerical properties of the desingularized boundary integral formulation were studied within the framework of free surface potential problems. Several numerical experiments were carried out on simple test cases in order to investigate the effects on the accuracy of the distance between the singularity sheet and the free boundary. The optimum value of this distance was related to the mesh size by simple correlations. Once the desingularized boundary integral formulation had been so calibrated, it was implemented for the solution of two typical free surface ¯ow problems: wave diffraction around a ®xed obstacle and wave resistance of submerged bodies. Numerical results are discussed in comparison with experimental data; the computational ef®ciency and accuracy of desingularized algorithms are con®rmed and speci®ed # 1977
