| Abstract: | In combination with corresponding boundary conditions, the hydraulic turbulence calculation for the tailwater tunnel system with a sloping ceiling shared by two units was studied with a unified method, in which the characteristic line method for pressurized conduits, the improved slot method for open channel by tracing the separation points of free flow and full flow, and numerical method of state equation were combined. The comparison of the result with that of the tailwater surge tank scheme shows that the hydraulic turbulence in the tailwater tunnel system has little influence on the stability of operation and regulation quality of units. The results provide a reliable basis for selection of the tailwater tunnel scheme with a sloping ceiling. |
