Tech., Xi´an 710055, China) Abstract: Numerical simulation method is used to study the dam tunnel of Shisanling Hydropower Station. The mathematical model of this tunnel is built, and the numerical simulation results by using this model are basically conforms with the data measured at the site. Using the validated calculation model, the dynamic heat transfer between dam tunnel and the outside air is studied, and the energy saving potential is predicted under the summer operational condition. In addition, the influence of tunnel length on heat transfer effect also is analyzed. The current results of dam tunnel ventilation of Shisanling Hydropower Station can provide a theory reference for energy saving design and regulation of underground powerhouse ventilation or air conditioning system.
