Abstract

Abstract: For the sake of wider application and promotion of positive pressure foam extinguishing technology, current researches on this technology are reviewed. Firstly, application advantages of the technology and both advantages and disadvantages of several gas-liquid mixing chambers were summarized. Secondly, types of spoilers and gas supply modes in gas-liquid mixing chambers were summarized. Finally, major studies on extinguishing performance and flow characteristics of positive pressure foam were outlined and evaluated.The results show that gas-liquid two-phase flow is most fully mixed in coaxial mixing chambers and conical spoilers, and liquid nitrogen source supply mode has the strongest foaming ability while aspirating gas source supply mode has the weakest one. Researches on foam extinguishing performance both at home and abroad mainly focus on fire extinguishing categories and foaming agent types, and those on flow characteristics of foam in tubes concentrate on foam rheology and its resistance loss.

Key words: positive pressure, foam, gas-liquid mixing chamber, spoiler, foam performance, foam fluid
