| Outline of Final Research Achievements |
In this research, we have developed a new propeller design method which can optimize propeller shapes and ship stern wake distributions. Both of wake distribution optimization and propeller shape optimization problem are transformed as a mixture optimization problem. In wake distribution optimization problem, we have used Blending method for stern hull shape to handle as a function optimization problem. In order to solve the propeller shape multi-objective optimization problem, a new propeller shape optimization algorithm using adaptive differential evolution (JADE) was developed. Propeller open water tests and cavitation tests were conducted using a model propeller designed using the developed system. Through experiments, we confirmed the improvement in propeller efficiency and reduction in cavitation.
