THE PUBLISHING HOUSE PROCEEDINGS OF THE ROMANIAN ACADEMY, Series A, OF THE ROMANIAN ACADEMY Volume 9, Number 3/2008, pp. 000–000 THE COMPUTING OF THE DAMPING GENERALIZED COEFFICIENTS

The ship hull forms have been described by the well-known classic Lewis transformation, Lewis in 1929, and by an Extended-Lewis transformation with three parameters, as given by Athanassoulis and Loukakis [4] in 1985, with practical applicability for any types of ships. We present here an algorithmic method solving directly the problems that appear in naval architecture domain concerning the contour of ship's cross-section. The application was made in Java language and creates both a text file and a graphical chart.With this algotithmic method in section 4 we propose a method for determining the adherent mass coefficients and in section 5 we compute the damping generalized coefficients. Key words: hydrodynamic ship cross section, Lewis transformation, area of the cross section 1
