Impact of Acoustics Impingement on Proliferating Fires

Forest fires are one of the major ultimate to natural and human established environment and have shown a tendency to rise in recent years. One of the crucial issues for a forest fire is associated with the combustion and propagation process. Researchers have been appraising new methods to control and diminish the repercussion of concurrent fires such as forest fires, building fires, and various space fires, but no captivating approach has been deduced from their studies so far. The key sources of these kinds of fires scrutinize the unstable nature of the flames and the strong unpredictability connected with them. Through proper experimentation, the effect of sound on the spreading of flames is investigated in the aid of spread rate. The present work is motivated by the superior standards of fire safety from practical and functional significance as it covers a wide range of engineering and industrial applications. Appreciable work had been carried out; however, the effect of sound on flames in a purely natural convective environment is an aspect yet to be thoroughly understood. The main objectives of the project are to study the fire propagation phenomenon in presence of acoustics and to fundamentally understand the role of key controlling parameters. The present work attempts physical insight into the effect of sound frequency, sound source distance, and a number of acoustic sources on the spreading of flames in opposed and concurrent configurations. An experimental setup was upraised comprising of a sound source with essential controls. The frequency of sound source and number of external sources are systematically varied keeping the ignition front fixed. The result advocates the significant effect of acoustics on the fire propagation phenomenon in distinct modes.
