Investigation on Optimization Strategies for the Hydrodynamic Design of DTMB 5415

The paper contributes to the field of ship design by investigating the applicability of formal strategies to the optimization of a ship’s hydrodynamic performance. A study on the geometric modeling, hydrodynamic analysis, design evaluation and shape variation of a DTMB5415 is presented. Optimization Algorithm is utilized to explore the design space and to improve the hull shape. The hydrodynamic design process is implemented: An advanced parametric modeling kernel is applied for efficient form generation and variation. The hydrodynamic performance is analyzed by state-of-the-art Computational Fluid Dynamics (CFD) codes for calm water resistance. A commercial optimization system is used to integrate the various CAD and CFD tools and to carry out the optimization.
