Design of ship's bow form by potential-based panel method

Trim Optimization of Ship by a Potential-Based Panel Method

“…The solution (1) is substituted into (13) to get the second approximation of Δ , that is, Δ (2) . This procedure is repeated until (13) and (15) are satisfied to a given error tolerance. The iteration numbers are about 5∼10 in this study for a certain tolerance of = 1.0 × 10 −6 in the present program procedure.…”

“…A method for verifying a critical aspect of numerical prediction of fully nonlinear free-surface flow around ship hulls steadily advancing in calm water is given by [10] Noblesse et al Tarafder and Suzuki [11,12] developed a potential-based boundary element method to investigate the influence of the water depth and the wave interference effects on the first-and second-order wave resistance of a catamaran hull. At the same time, a surface panel method treating a boundary-value problem of the Dirichlet type with free surface was presented to design a three-dimensional body by Yoo [13]. The free surface boundary condition was linearized with respect to the oncoming flow and computed by four-point finite difference scheme.…”

Research on a method of hull form design based on wave-making resistance optimization

“…In order to obtain a hull with the minimum wave-making resistance, designers often try to make improvement of parent hull. This requires lots of ship design experience, without mentioning the uncertain improvement [21]. Chen and Guang [2] optimized the shape of the after hull based on the desired wake distribution, using B-spline surface method to generate the surface geometry of ship.…”
