| Summary: | The higher thermodynamic efficiency inherent in a detonation combustion based engine
has already led to considerable interest in the development of wave rotor, pulse detonation, and
rotating detonation engine configurations as alternative technologies offering improved
performance for the next generation of aerospace propulsion systems, but it is now important to
consider their emissions also. To assess both performance and emissions, this paper focuses on the
feasibility of using alternative fuels in detonation combustion. Thus, the standard aviation fuels Jet-
A, Acetylene, Jatropha Bio-synthetic Paraffinic Kerosene, Camelina Bio-synthetic Paraffinic
Kerosene, Algal Biofuel, and Microalgae Biofuel are all asessed under detonation combustion
conditions. An analytical model accounting for the Rankine-Hugoniot Equation, Rayleigh Line
Equation, and Zel’dovich–von Neumann–Doering model, and taking into account single step
chemistry and thermophysical properties for a stoichiometric mixture, is applied to a simple
detonation tube test case configuration. The computed pressure rise and detonation velocity are
shown to be in good agreement with published literature. Additional computations examine the
effects of initial pressure, temperature, and mass flux on the physical properties of the flow. The
results indicate that alternative fuels require higher initial mass flux and temperature to detonate.
The benefits of alternative fuels appear significant. |
