Abstract: Process of extinguishing, expansion, and controlling of the fire flames by acoustic action, where utilizes the pressure alteration causing rarefactions and compressions in the particles generated by the acoustic waves in a combustible, oxidizing, or mixed environment. The factors that influence the control of the flames intensity are: AMPLITUDE, the FREQUENCY and the STANDING WAVE MODE. The standing wave produces two effects: the node and the womb, so the position of the node we get the flame extinguished and the position of the womb to increase the flame. When the rarefactions frequency and amplitude are greater than the burning rate then the flame is diminished until it is off. When the resonance occurs (?=?0) between the flame's natural frequency (?0) and the sound emitted (?) there is the combustion extinguishing, when (?) is close to (?0) there is an increase of flames (?0).

Abstract: The present method and apparatus for producing a supersonic jet stream introduce an oxidizer in such a manner as to create a vortex, which is then restricted. Fuel is introduced into a reduced pressure eye of the vortex, forming a stratified composite stream of gases with unmixed oxidizer surrounding an inner mixture of fuel and oxidizer. This stratified composite stream is passed down a tube that exhausts to a low pressure environment. The combined fuel and oxidizer in the stratified stream is ignited to provide a high-velocity stream of combustion products. The outer layer of unmixed oxidizer in the vortex shields the tube and reduces or eliminates the need for additional cooling.
