“…Recent enhancements about extinction effectiveness of premixed methane-air flames by water mist have been brought in by Parra et al [34] from a purely numerical point of view. The authors focus on a one-dimensional model, where the water flow is subjected to the following subsequent phenomena: dragging, breakup, heating and vaporization.…”

Abstract:The present work is an attempt to offer a comprehensive review of literature contributions, phenomenology and relevant results on water-mist systems. In particular, the water mist characterization and behavior in the field of fire control and suppression have been identified as the main areas of investigation. Some key parameters have been analyzed to gain a quantitative evaluation of the physical phenomena related to water-mist systems.The water-mist fire suppression systems are an excellent alternative to halon fire protection systems, and they are now being used in many areas, including marine and industrial applications. Therefore, a wide survey of the complete number of literature works on this topic would exceed the full length of the present paper and only some examples of important contributions will be mentioned here. This paper proposes an introductory list of relevant literature works and this reference survey is then deepened with work and result details on suppression mechanisms, spray characterizations and experimental and numerical approaches. The final summary stresses out that a lot of experimental and numerical research and much application experience are still needed to gain better knowledge on water-mist systems, even if they already seem to be very promising in terms of efficiency and potentialities in fire control and suppression.

“…The heat transfer mechanisms between a methane-air flame front and a water spray or mist have been fully described by Parra et al [4]. Besides the flame extinction mechanisms [5,2,6] and the mitigation effects of the spray [7][8][9][10][11][12][13] are characterized for methane-or propane-air flame.…”

The effects of obstacles on methane explosion inside a narrow space and its suppression by ultra-fine water mist are investigated experimentally. Two PCB pressure transducers and two E12-1-C-U fast response thermocouples are used to obtain the explosion pressure and temperature, respectively. A Fastcam Ultima APX high speed video camera is used to visualize the process of methane explosion with the influence of obstacles and ultra-fine water mist. The results show that the explosion would be strengthened by the obstacles, while the further strengthening occurs to the cases where the obstacles are farther from the ignition electrode. In addition, the more the obstacles are, the stronger the explosion strengthening will be. The reinforcement effect on gas explosion of the square ring is a little stronger than the column one. The suppression of methane gas explosion containing obstacles with ultra-fine water mist is very effective. KEYWORDS: gas explosion, explosion overpressure, explosion suppression, water mist
