Radical Representations of Ship Simulations.
Abstract
Straight lines, circles, and splines are used in most mathematical representations of ship lines. The representations are only piecewise analytic. Discontinuities in curvature occur along waterlines and section lines. The discontinuities upset computations of velocity distribution in the flow around the ship. The discontinuities are smoothed when the lines are approximated by orthonormal polynomials. The discontinuities are eliminated when the lines are simulated with the aid of radicals. A smooth simulation of the Series 60, Block 0.60 ship model is given by a radical representation. (Author)
