- Abstract:
- On a full scale experimental tower with height of 122.9 m, special ventilation and drainage system with H pipe connected each floor with different ventilation modes (extended top ventilation or side wall ventilation) at the top of the drainage pipe was compared. The influence of the top ventilation modes on pressure and ventilation flow in the drainage system was explored, so as to study its effect on the drainage capacity of the special ventilation and drainage system. Compared with extended top ventilation, side wall ventilation led to a reduction of the minimum pressure (Psmin), ventilation flow (Q2) into the top of the special vertical vent and drainage capacity of the system.
