Abstract: Based on the optimized S-type aerosol fire extinguishing agent formula, the fire extinguishing performance of S-type aerosol fire extinguishing agent in smoke chamber was tested, the similar curve model was obtained through FDS software simulation. A similar curve model was obtained by simulating the extinguishing time of aerosol fire extinguishing agent at different space locations. The maximum temperature of simulated aerosol fire extinguishing agent is between 500 ℃ and 600 ℃, which is consistent with the experimental data measured by infrared imager.

Key words: FDS simulation, gas flow, fire extinguishing performance
