Numerical Simulation Of Dynamic Heat Transfer About The Corridor In Dam Of Dagangshan Hydroelectric Station

Conventional model is used for underground building's ventilation and heat transfer calculation of hydroelectric station usually. This paper studied the dynamic numerical simulation of heat transfer about the hydroelectric station's corridor in dam. It could realize dynamic changing calculation about the heat change of system instead of the conventional method.Considering the marked characteristic and the powerful function about the CFD software, this paper choose FLUENT as simulation platform and simulated the system of whole year. This paper developed a new kind of software for heat transfer numerical simulation of underground building. The simulation analysis about the heat change of system during five years was made. The analysis and study result shows that the numerical method is effectiveness and feasible through comparing and analyzing the numerical value and the conventional calculation. This special software could reduced calculation time and make the project design easy. It can provide the information for project design and administration.
