| Abstract: | Three dimension turbulent flow in forebay of pumping station is numerically simulated with finite volume method and hybrid grid technique. The hybrid grid system consists of orthogonal body fitted curvilinear coordinate in horizontal dimension and Cartesians coordinate in vertical dimension. Two numerical computation examples were adapted to test the simulating method and simulated results were compared with experimental data. The primary results showed that the hybrid grid method and corresponding mathematical model are especially suitable for simulating complicated flows in forebay of pumping station, in which bottom sill, diversion wall and underwater piers were installed. |
