Flow- and Wave-Field Optimization of Surface Combatants Using CFD-Based Optimization Methods

This paper concerns flow- and wave-field optimization of surface combatants using CFD-based optimization method. The main focus is placed on development of a high performance optimization module for application to Model 5415 hull form optimization, which is capable in combination with CFDSHIP-IOWA version 3.02, a RANS solver based on higher-order upwind finite difference and a projection method for velocity-pressure coupling. The optimization scheme is based upon the work of part of the present authors wherein tanker hull forms were optimized for minimum viscous resistance. The module is general in formulation, and basically independent from basic flow solver, e.g., different Reynolds Averaged Navier-Stokes (RANS) solver or inviscid-panel method can be used with arbitrary combination of constraints and objective function to be minimized. In the following, an overview is given of the present numerical method and results are presented for flow- and wave-field optimization of surface combatant Model 5415 hull form.
