Resumen:
A closed form for the computation of the dipolar and monopolar
influence coefficients related to a low-order panel method is shown.
The flow problem is formulated by means of a three-dimensional
potential model; the method of discretization is based on the Morino
formulation for the perturbation velocity potential. On the body
surface this representation reduces to an integral equation with the
source (or monopolar) and the doublet (or dipolar) densities. The
former is found by application of the boundary condition, and the
latter is the unknown over the surface of the body. The lower panel
method is used for the analytical integrations of the monopolar and
dipolar influence coefficients, with special attention to avoid a
logarithmic singularity in the monopolar matrix when flat fairly
structured meshes that are common in ship-wave calculations are used.
