Effect of sound on a turbulent flame
A theoretical analysis shows that the nature of the stability of a gas jet depends significantly on the location of the flame front and on the ratio of the densities of the combustion products and the fresh mixture.
It has been experimentally established that there is an analogy between the sensitivity of a turbulent flame and a jet of unignited gas to sound. Eddy formation in flames takes place in the presence of weak acoustic oscillations, whose energy density is a millionth of the kinetic energy of the gas flow.
