Abstract

Because of complex shape and multiple working faces, it’s difficult to ventilate and dissipate smoke in the large gallery-type surge chamber of Luding Hydropower Station. To improve the ventilation and secure the construction, a numerical simulation method based on fluid mechanics theory is applied to the research of airflow distribution and harmful gas diffusion of different ventilation options in the first and second construction stage. The optimum ventilation scheme of the first and second construction stage is given, and the corresponding reasonable time of ventilation and smoke dissipation is put forward. The research result serves as a theoretical basis and technical support for the determination of ventilation time in the construction of hydropower station.

Key words： Luding hydropower station; large gallery-type surge chamber; fluid mechanics; 3-D numerical simulation; ventilation and smoke dissipation
