Flow Analysis around the Bang-o-Jin Breakwater by Numerical Simulation

수치계산을 통한 방어진 방파제 주위의 유동장 해석

The flow analysis around the Bang-o-jin breakwater was carried out by the numerical simulation based on the package program NISA Ⅱ. The averaged Navier-Stokes equations are changed to a weak formulation, which is an application of finite element method. To get a better circulation of sea-water current, various types of breakwater modification were numerically tried for the purpose of comparisons. According to the numerical results, it proved to be very difficult to have the seawater circulate in every corner inside the breakwater. However, some cases give the promising feasibility provided that the waste water disposal plant should be additionally made.
