Genetic Algorithm Optimization of a Ship's Bulbous Bow

A genetic algorithm technique coupled with a potential flow solver has been applied to deal with the hydrodynamic optimization of a bulbous ship hull form. A non interactive procedure has been developed to minimize the objective function, related to the flow past a ship moving with steady forward speed in calm water. A Bézier surface, defined by several bulb geometrical parameters, has been used to model the forebody and to allow the modifications. According to the geometrical constraints, a new optimized hull form has been automatically obtained. The hull form with the obtained modification of the bulb has been presented and analyzed in order to demonstrate the effectiveness and validity of the developed procedure.
