Abstract: For the purpose of avoiding the deficiency of the traditional construction ventilation, the ventilation of the underground main powerhouse is simulated by the computational fluid dynamics (CFD) to optimize ventilation parameters.
Consequently, the investigation of CFD simulation of the underground powerhouse construction ventilation is of great significance.
Due to the complexity of construction ventilation in the underground caverns, numerical simulation studies on the construction ventilation of the hydropower station underground caverns have been conducted gradually in recent years.
However, numerical simulations of ventilation have mainly concentrated on the single tunnel, with less attention given to the construction ventilation of underground powerhouse.

Besides the experimental techniques by using wind tunnel in natural or reduced scale, CFD simulation method is more and more wildly adopted to optimize the aerodynamic performance of EV because of the great development of hardware and software [5~8].
The fluid dynamics simulations have been executed using the commercial CFD tools Fluent 12.0 in order to capture the characteristics of the flow field around concept EV models.
