The performance of air curtain was evaluated on the basis stability of air jet at higher different pressure difference across the door. Here in this work it calculate the effect of different pressure difference on air jet stability, for calculating the effect of different pressure difference here in this work it considered six different pressure difference that is 1, 4, 6.25, 9, 12.25 and 16 Pa. at each pressure difference it calculated the value of volume flow rate of smoke at outer outlet. It also calculate the effect of different air jet angle on the volume flow rate of smoke, for analysing the effect of different air jet angle here it considered five different air jet angles that is 10, 15, 20, 25 and 30 degree. Through analysis it is found that at 25 degree air jet angle the performance of air curtain is higher as compared to other angle. After analysing the effect of different air jet angle, it also analysed the effect of different air jet velocity on volume flow rate of air, for analysing the effect of different air jet velocity it considered four different air jet velocities that is 8, 10, 12 and 13.5 m/s and calculates the value of volume flow rate of smoke for each velocity at different pressure difference.
