Conclusions
-
1.
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.
-
2.
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.
