| Research Abstract |
A method to optimize propeller performance in ship stern wake has been developed. In the present method, unsteady calculation method of propeller characteristics is used for evaluation of propeller performance in ship stern wake. Real-coded genetic algorithm is used for optimization procedure. Three different objective functions about propeller performance were used for optimization. Improved propellers that have superior performance comparing to original propeller were obtained in each case. In the present calculation, positive correlation between propeller efficiency in uniform flow and propeller performance in ship stern wake was found.
