The use of fine water mist as a possible Halon 1301 replacement for certain fire suppression applications has been discussed by Jones and Nolan and by Ramsden. One current research effort is to apply the water mist sprays to suppress the fire occurring in hidden location behind obstructions or inside the equipment compartments. This study presents an integrated approach to model the penetration of water mist through the obstructions for fire suppression applications. The objective is to reveal the transport mechanisms, impacting dynamics, and penetration of mist droplets through the obstructions during fire situations.
