Tunnel fires are responsible for many fatalities in recent decades and this field of study has received an extensive effort by researchers. Most of deathes in these events are attributted to inhalation of toxic gases such as CO rather than high temperature of fire which causes 15 to 25 percent of deaths. Removal of the generated plume or its dilution and reduction of high temperature are the great interest of investigators. In the current study, a numerical test has been performed on a rectangular cross section tunnel of 600m length, 10m width and 7m height with a pool fire at the middle part using FDS5.5. Obtained results were compared with previous theoretical and experimental results. After satisfying a good agreement with prior results, single and couple air curtains were used to investigate their efficiency on dilution of the amount of toxic gases and high temperature. Results show that double air curtain is better than a single one and can decay the relevant amounts of CO and temperature below the standard values.
