Source distribution method and hydrodynamics coefficients of vessel

Abstract

In the present research, fix structure and floating structure such as vessel are studied in terms of hydrodynamics forces and hydrodynamics coefficients. Currently, three-dimensional source distribution method is adopted which taking into account the actual design offzx structure as well as hull form. A curved triangular boundary element is implemented with constant source distribution on each element. Some improvements are adopted in order to solve the singular integration of elements. Gauss-type Laguerre integration as well as cauchy principal value are implemented to solve the Green function numerically. These modification show some improvement ofaccuracy according to number ofpanels. Experimental result of Greek passenger ship is compared with present result as well as Frank Close-Fit Method.
