abstract
Fuel/air mixing enhancement inside the combustion chamber will depend on the strategies used to control the fuel jet penetration and liquid fuel droplet size, trajectory, and dispersion. We present in this paper experimental results on the mixing of aerated liquid transverse jet in supersonic cross flow. Transverse aerated liquid jet injection will offer relatively rapid near-field mixing and good fuel penetration and fully modulated or pulsed fuel jet injection will introduce additional supplementary turbulent mixing. Better atomization of liquid fuel is obtained by using aerated liquid fuel injector. High speed imaging system is used in this study for the visualization of the penetration of liquid jet in cross flow and the Shadowgraphy technique is used for the measurement of the size of the liquid droplets. The results presented in this paper show the effect of pulse injection frequency, duty cycle and gas/liquid mass ratio on liquid fuel atomization and dispersion. The data generated in this study are used for the development of active control strategies to optimize the liquid fuel jet penetration and fuel/air mixing at supersonic conditions Copyright © 2005 by the American Institute of Aeronautics and Astronautics, Inc.
