Generated turbulence and deflagration-to-detonation transition is established. Measurements of the flame turbulent speed and turbulent Mach number, transition into a non-linear compressibility regime at turbulent Mach numbers above 0.4 is confirmed, and a possible mechanism for flame The turbulent flame speed is directly measured for the high-Mach standing turbulent flame. Turbulent velocities, vorticity and turbulent strain are provided for regions ahead and behind the standingįlame. Turbulence interaction for high levels of turbulence at elevated temperatures and pressure. Highspeed schlieren, chemiluminescence, PIV, and dynamic pressure measurements are made to quantify flame– In this paper we present the first measurement of turbulent burning velocities of a highly turbulent compressible standing flame induced by shock-driven turbulence in a Turbulent Shock Tube.
