Abstract: The standard k-ε turbulent model is employed to simulate the flow field of conveyance system in the Three Gorges Project. VOF method is used to track free surface in the valve well. The method has been verified and applied to simulate flow field of two structure schemes: top expanding and bottom expanding. The numerical results are demonstrated in real time way. It shows that the recirculation appears larger behind the valve gate in the bottom-expanding scheme than that in the top one; and the turbulence in the well of valve is strong while the velocity is quite limited. Hydraulic parameters such as water level and velocity have been obtained by the numerical simulation method in any arbitrarily points. The present work provides a foundation of cavitations in the two-way five-step ship lock.
