Outline of Final Research Achievements

As an energy saving of the ship, a method of installing energy saving device to the ship hull has been devised. In this study, in order to aim a high efficiency of energy saving duct, the duct model made of a transparent material that can be refractive index matched to the water, we developed a technology to measuring the duct external and internal detailed flow field. Furthermore, the forming method of the three-dimensional shape like the duct was examined. In present modeling method, production of the model of the three-dimensional shape was difficult. Therefore, to investigate the influence on the flow field measurement due to the difference in refractive index by using a flat plate made of a transparent material, but found no difference. In the future, we want to be aim at the practical application of flow field measurement technique in model internal and external flow of duct by the refractive index matching method.
