We use CFD to simulate fire and smoke spread in buildings, warehouses, exhibition halls, industrial and mining plants, oil and gas platforms and hangars, size smoke control and extraction, and check visibility along escape routes. The results support design and fire department approval.
Smoke control by pressure differential. With CFD we found the ideal pressure gradient between floors and the extraction flow rate on the fire floor, keeping the other floors at positive pressure so smoke does not spread.
Construction had been halted. We simulated a wood and plastic fire with an HRR of 8,000 kW and visibility on all four sides of the hall up to 3,600 s after ignition. The design was approved by the fire department.
“ATS4i carried out several CFD studies in fire engineering, with results accepted and approved by the technical staff of the São Paulo Fire Department. This work supported further advanced fire engineering studies that are changing, significantly and permanently, concepts in Brazilian fire department regulations.”
