비선형 조파문제를 위한 패널법과 유한체적법의 비교연구

The two different approaches for solving the nonlinear ship wave problem are discussed in the present paper. The first one is based on a panel method which neglects the viscous effects. Another one is based on a finite volume method which solves RANS equations. The present paper has been focused on the advantages/disadvantages of the above two methods. The developed methods are applied to calculating the flow around Wigley hull & Series 60 hull to validate the performance of the present nonlinear method. Although the two methods employ quite different numerical approaches, the calculated wave patterns from the both methods show good agreements with the experiments.
