Initiation, Stability and Limits of Detonation for Advanced Stable Airbreathing and Hybride Propulsion Engine Design.

Abstract

The influence of orifices on the propagation of flames in tubes has been investigated by measuring flame speeds and pressure on both sides of the orifice and by taking smear camera pictures of the flames passing through the orifice. In addition the jet ignition process was stimulated by igniting high speed jets of turbulent unburned gas with electric sparks. Pressure-time profiles and smear camera pictures give information about the flame speed in gases with very high degrees of turbulence. Originator furnished keywords include: Flames, Combustion, Detonation, Orifice plates, Initiation, Stability.
