Detonation is a high energetic mode of pressure gain combustion. Detonation combustion exploits the pressure rise to augment high flow momentum and thermodynamic cycle efficiencies for high thrust propulsion. The driving mechanism of deflagrated flame acceleration to detonation is turbulence generation and induction. http://mae.ucf.edu/PERL/

Student Responsibilities
The investigation will explore physics-based flow control strategies to enhance flame acceleration to detonation. In order to assess the quantitative importance of the flow mechanisms on the flame-fluidic interaction and instability of a jet in crossflow, the jet conditions must be independently controlled. Three strategies are proposed to achieve this: jet boundary layer tailoring, fluidic actuation (upstream suction or injection), and jet excitation. These strategies will allow active control of the interaction shear layer. A partial test section modification with additional capability will accommodate these concepts. The modification will allow for a more complete analysis of the flame interaction. The turbulent flame-flow interactions are experimentally studied using a LEGO Detonation facility. Advanced high-speed laser diagnostics, particle image velocimetry (PIV), planar laser induced florescence (PLIF), and Schlieren imaging are used in analyzing the physics of the interaction and flame acceleration.
