Detonation Physics for Propulsion Applications
Abstract
The main thrust is to understand the sensitivity of detonation wave dynamics to physical scaling of the combustion waveguide. Device geometry aects the large-scale chamber dynamics as well as the small-scale internal wave dynamics in each principal direction. The technical objectives of the project are delineated accordingly, by scaling dimension- the radius of curvature, the axial length, and the channel width. Experimental measurements of detonation dynamics will be acquired through three series of tests. The axial length and channel width will be varied continuously using a unique experimental RDE that can support active geometry change during a combustion test. A second experiment will be developed to continuously vary the channel curvature and explore the potential for non-circular waveguides. Finally, two linear rectangular channels will be used to characterize the structure and dynamics of triple points that manifest the global properties of the detonation wave. Through this project, we will directly tackle fundamental, relevant questions in high-speed combustion physics and develop a physically accurate scaling methodology for continuous detonation combustion devices with propellants and flow conditions of practical importance.
