Abstract

In this paper, the wave pattern around the hull with the transom stern advancing on the free surface with a constant speed was taken into consideration. To solve the problem the numerical analysis program was developed using Rankine source panel method based on potential flow analysis technique. The non-linearity of the free surface boundary conditions was fully satisfied. To verify the validity of the developed program the numerical calculations for Athena hull and KCS(KRISO container ship) hull was performed. The results of the numerical computation was compared with the ones of the model test experiment.

본 연구에서는 자유수면 위를 고속으로 항주하는 트랜섬 선미를 채택한 선박에 의하여 발생되는 선박주위 및 트랜섬 선미 끝단에서의 비선형 자유수면 경계조건식을 만족하는 자유 수면에서의 파형을 해석하는 수치해석 기법에 대하여 연구, 선체주위 유동해석프로그램을 개발하였다. 개발된 수치해석 프로그램의 타당성을 검증하기 위하여 고속선인 Athena선형, KCS(KRISO container ship)선형에 대하여 수치해석을 실시하였으며, 그 결과를 모형시험에 의하여 계측된 실험결과와 서로 비교하였다.
