초록

This study presents the wave run-up height and depression depth around offshore cylindrical structures according to the wave period. The present study employs the volume of fluid method with the realizable turbulence model based on a commercial computational fluid dynamics software called the "STAR-CCM+" to simulate a 3D incompressible viscous two-phase turbulent flow. The present results for the wave run-up height and depression depth with regard to the wave period are compared with those of the relevant previous experimental and numerical studies.
