공기저항을 고려한 고속 경비정 개발에 관한 연구

Abstract

'The United Nations Agreement in Law of the Sea' which was come into effect in 1994 defines the oceanic jurisdiction for all nations. It established the principle of a 200-nautical mile limit on anation's exclusive economic zone (EEZ) where by a nation controls the undersea resources, primary fishing and seabed mining for a distance of 200 nautical miles from its shore. In case of declaration, a solution should be approached fairly by mutual consent that makes a border if the EEZ overlaps with other countries.

In this study, a plan for improve of resistance performance which 100ton class high speed patrol boat

1) select the primary 100ton class high speed patrol boat

2) Model test in towing tank for check the performance of primary 100ton class high speed patrol boat

3) Using CFD code Shipflow, check the wavefattern, pressure distribution and Total resistance (compare with model test)

4) Using DNS, check the air resistance of primary 100ton class high speed patrol boat

5) Design of new Deck house (change the attack of angle 30°, 45°, 30°+45°)

6) Using DNS, check the air resistance and flowpattern around the deck house (3 Case)

7) Calc. the Total resistance and compare the each cases.

8) Conclusion
