Abstract
This study present numerical investigation for designing impulse ventilation system to manage smoke produced due to car on fire in underground workshop at car service center. By studying effect of changing different variables on visibility, temperature and velocity at human level to insure not to exceed limits stated by NFPA to apply evacuation plane. The study is performed using FDS to simulate 13 case studies in workshop its dimension is 50m{u00D7}25m{u00D7}4.5m.The workshop contain random distribution of cars, paint furnace and paint store
