Abstract

This study investigates the characteristics of stem waves along a vertical wall generated by obliquely incident monochromatic waves through laboratory experiments conducted in a wave basin and numerical simulations using parabolic approximation equations. The investigation is focused on the nonlinear effect of incident waves on the propagation characteristics of stem waves. Numerical results are compared with laboratory measurements and good agreements are obtained. The main results of this study show that the normalized stem wave height along the wall decreases and the stem width increases as the angle of incident waves decreases or the nonlinearity of the incident waves increases.

본 연구에서는 직립벽을 따른 규칙파의 연파특성을 평면수조를 이용한 수리실험과 포물형근사식을 이용한 수치해석을 통해 검토하였다. 본 연구는 파랑의 비선형성이 연파의 전파특성에 미치는 영향을 검토하는 것으로서 수리실험결과와 수치해석 결과가 잘 일치함을 알 수 있었다. 본 연구로부터 입사각이 작아지고 입사파의 비선형성이 증가할수록 연파의 파고는 감소하고, 연파의 폭은 증가함을 알 수 있었다.
