Active Control of Unsteady Gasdynamics for Shock Compression and Turbulence Generation

Abstract

An important research area in propulsion science today involves transient processes. Steady state combustion has long been studied and used in engines, but transient processes are now being examined to determine their abilities in propulsion systems. One of the main ideas for transient propulsion involve pulsed detonations, and are referred to as pulsed detonation engines (PDE). Although the theory behind their use is sound, the implementation can be quite dangerous due to the high pressures involved with their operation. A safer approach to creating the transient pressure waves may be found using pulsed supersonic flames. The present work will examine the creation of a pulsed supersonic flame through actuation of the incoming oxidizer.
