  2. Air inlets Boundary conditions / assumptions: • Only SEVS system • Extraction in TR3-TR8, 30 000 m3/h each • Air inlets in the galleries corresponding to TR1 and T2 • Two cases! With 25 000 m3/h injection in the center and without Smokeextractors 2013-02-01

  3. 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) 2013-02-01
