Numerical Analysis on Wave Breaking Around a Wedge-Shaped Bow

ABSTRACT Koo, B. and Kang, Y.-D., 2021. Numerical analysis on wave breaking around a wedge-shaped bow. 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. 559–563. Coconut Creek (Florida), ISSN 0749-0208. Numerical study has been performed to investigate the flow characteristics such as wave breaking process and small scale features of ship bow waves. The geometry of wedge-shaped bow used in the present study is from one of previous studies (Waniewski, Brennen, and Raichlen, 2002) and the condition of calculation is with Re = 1.64×105 and Fr = 2.93. Star CCM+, one of commercial CFD softwares, has been used to perform the numerical simulations. Results such as overall bow wave profile, plunging jet shape, air entrainment, and wave breaking process have been compared with other experimental and numerical studies and discussed some discrepancies with others.
