Lee, J.-H. and Koo, B., 2021. Numerical study of non-linear wave run-up around a circular cylinder in regular waves. In: Lee, J.L.; Suh, K.-S.; Lee, B.; Shin, S., and Lee, J. (eds.), Crisis and Integrated Management for Coastal and Marine Safety. Journal of Coastal Research, Special Issue No. 114, pp. 554–558. Coconut Creek (Florida), ISSN 0749-0208. In this study, numerical simulations have been carried out to investigate the non-linear wave run-up phenomena of a single cylinder according to wave period and slope. In order to perform numerical analysis on a three-dimensional incompressible viscous turbulent two phase flow, this study used a Volume Of Fluid (VOF) technique and a realizable turbulence model based on the Computational Fluid Dynamics (CFD) commercial code, “STAR-CCM+”. Various incoming wave conditions have been applied to see how the wave steepness and wave periods affect the wave run-up height on the circular cylinder. Finally, the wave run-up estimation results for wave slopes and periods were compared with the related experimental results and they had good agreement. It was confirmed that as the wave steepness increased, the run-up phenomenon appeared largely at the part where the cylinder hit the incident wave.
