| Abstract: |
| In the present study, a new algorithm-BFC-SIMPLE-VOF method based on VOF method was developed to model the flow field around the complex structures. Structured grids are achieved by the orthogonal coordinate transform method in the arbitrary complex region.The two-dimensional incompressible viscous flow was analyzed by solving Navier-Stokes equations on body-fitted curvilinear grids. The transformed SIMPLE scheme was adopted to modified the pressure-velocity field and the transformed VOF method was used to trace the free surface.The flow field and pressure field around the breakwater with curving wave wall were simulated using the new algorithm that was advanced in the paper, and was compared with the value that was achieved by the traditional rectangular grid which are approximated by steps. |
