A Bluntness Effect of Hull Form on Hydrodynamic Forces and Unsteady Waves of a Ship Advancing in Waves

概要

論文の詳細を見る
The bluntness effect of the hull form is investigated by comparing numerical results with experiments for a Series-60 slender model (C_b=0.6) and a blunt model (C_b=0.8). The numerical method used in this study is a desingularized Rankine panel method which enables exact treatment of the steady wave field in the computation of the unsteady problem. The unsteady problem is solved taking into account the influence of the fully nonlinear steady wave field through the free surface and body boundary conditions. Numerical results for the hydrodynamic forces are compared with experimental data and strip method. Discussion are made on the bluntness effect of the two hull forms on hydrodynamic forces, steady and unsteady wave fields.
