E. Da Riva, S. E. Wojnarska PS Ventilation - Smoke extraction -

E. Da Riva, S. E. Wojnarska Boundary conditions / assumptions:  Only SEVS system  Extraction in TR3-TR8, m3/h each  Air inlets in the galleries corresponding to TR1 and T2  Two cases! With m3/h injection in the center and without Air inlets Smoke extractors

E. Da Riva, S. E. Wojnarska Boundary conditions / assumptions:  Extraction: velocity ~5m/s, area 1,7m2 (velocity inlets)  Inlets: TR1: 3,0m X 3,4 m; TR2: 1,2m X 2,0m (pressure inlets)
