The turbulent flow past a circular cylinder has been studied extensively by previous researchers due to its importance in many engineering applications. In particular, the wave run-up is one of the most significant design factors when offshore structures are operated. In this paper, the wave run-up height and depression depth around a vertical circular cylinder were numerically investigated. The commercial CFD solver “STAR-CCM+” has been used for the numerical simulations. The models of K-epsilon turbulence and volume of fluid (VOF) are utilised to solve the Reynolds Averaged Navier-Stokes equations (RANS) and continuity equations, respectively. Various Froude numbers and Reynolds numbers are utilised to observe the wave run-up height on the front of the cylinder and the depth of depression at the back. The results were compared with previous experimental data and theoretical values and were found to be in good agreement with other studies.
