Abstract
AbstractThis paper presents an innovative method of extinguishing of flames using a high-power acoustic extinguisher. This method allows for effective and non-invasive extinguishing of the flames. Experimental results showing the effectiveness of the fire extinguisher for different distances from the flame source and different frequencies of the acoustic wave are discussed. The paper ends with the description of the advantages, disadvantages, and limitations of the proposed fire extinguishing method.

IntroductionTraditional methods of fire extinguish are based on cutting off the oxygen supply from a burning surface
For many years, effective methods of fire extinguishing have been sought
In 2008, American Defense Advanced Research Projects Agency (DARPA), launched the Instant Fire Suppression (IFS) research programme aimed at a better understanding of the nature of sound waves in terms of their potential application in military applications
Summary
Traditional methods of fire extinguish are based on cutting off the oxygen supply from a burning surface. These include powder extinguishers, traditional water-extinguishers, and CO2 fire extinguishers [1, 2]. Air turbulence resulting from variable acoustic pressure breaks the continuity of the flame and leads to its extinguish [10, 11]. In 2012, the research team arranged two speakers opposite each other, to demonstrate the effectiveness of the extinguish process depending on the sound parameters of the acoustic wave [19]. It is related to that effectiveness of the extinguish process depends on the amplitude of the air vibrations. Another parameter that determines the effectiveness of the extinguishing process is the acoustic power
