A review of water mist fire suppression systems

Aspects concerning water mist fire suppression systems were reviewed and discussed. These included the suppression mechanisms, system classification, research and development, roles played by fluid dynamics, standards and fire test protocols, and performance-based design. As the suppression mechanisms of a water mist system depend on many factors, nominal flux density and nominal volume concentration available are not good enough to be used as parameters for a universal design method. The performance-based designs of water mist systems are still limited by the available fire test protocols. Further studies recommending new design parameters should be worked out to simplify the design procedure.
