On the generation of turbulence in highly transient combustion driven flows

In the present paper, the propagation of a flame through a liquid in a nearly spherically symmetric configuration is considered to illustrate the significance of the Taylor mechanism in the development of a turbulent wave front. The configuration involved a windowed bomb filled with hydrazine monopropellant and ignited with an electric spark. A framing camera sequence of reaction zone propagation, showing the development of the flame front in steps of 4 microseconds is presented. A significant result of the experiment is that a well-developed turbulent flame can be generated in a natural way in highly transient flow.
