| Abstract: | A new CFD model based on BFC was developed in this paper.Structured grids were 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 boundary-fitted grids.The VOF method was modified to trace the free surface.The pressure field and the time profiles of water surface near the arc crown wall were computed by the CFD model based on body-fitted coordinate(BFC).The results of the BF... |
