Abstract

The objective of the This study is to access the speed performance employing the sea trial test and CFD with the our own designed and manufactured one-man boat. The overall design process including hull form design was explained. The sea trial was carried out with a manufactured boat in the clam sea. Brake power at the design speed of a boat through the sea trial was measured as 1680 W. The flow computation was conducted considering free surface and dynamic trim using a commercial CFD code(STAR-CCM+). The result of computation provided the information that residual resistance is bigger than fraction's at design speed. The total efficiency were predicted based on the sea trial and CFD. The Total efficiency was divided into shaft efficiency and quasi-propulsive efficiency. By using quasi-propulsive efficiency, it becomes possible to predict speed performance of boat in future. The results can provide information regarding hull form design, performance analysis and development of a boat in future.

본 연구의 목적은 1인승 보트를 설계 제작하여 시운전 및 전산유체역학(CFD)를 이용하여 속도성능을 분석하는 것이다. 선형설계를 포함한 보트의 전반적인 설계과정을 설명하였고, 설계를 바탕으로 제작된 보트에 대하여 잠잠한 해상에서 시운전을 수행했다. 시운전을 통해 보트의 설계속도에서 제동마력은 1680 W가 계측하였다. 유동해석은 상용 CFD 코드인 STAR-CCM+를 이용하여 자유수면과 동적트림을 고려하여 수행되었다. 유동해석 결과 잉여저항 성분이 마찰저항 성분에 비해 크게 나타나는 것을 확인할 수 있었다. 시운전과 CFD 결과를 바탕으로 보트의 전체효율계수를 추정하였다. 전체효율계수는 전달효율과 준 추진효율로 나누었다. 준 추진효율은 동일 프로펠러를 사용하는 솔라보트의 속도성능 추정 시 사용될 수 있다. 연구결과은 향후 개발될 보트의 선형설계, 성능분석 및 개발에 정보를 제공할 수 있다.
