摘要:
Acoustic fields interacting with a rectilinear droplet stream flame can increase mixing between fuel and oxidizer. For a droplet stream burning in room temperature air, sufficiently high acoustic intensity levels can cause local flame extinction. The sound pressure levels required to extinguish the flame increase with increasing sound frequency. The key parameter associated with flame quench is the gas displacement produced by the sound field. Quenching occurs when the acoustic displacement distance is approximately the radius of the droplets fueling the droplet stream flame.
