摘要	The planar laser scattering and gas sampling were used to investigate the mixing of the excited CO2 jet into the supersonic flow in this article. The jet was from the Hartmann-Sprenger tube, which was put into the traditional jet device. The jet was excited at three different frequencies and compared with the base case without excitation. The results shown that the better mixing with less total pressure loss could be obtained in the excited cases. The penetration was the deepest for 900Hz-excited jet while the number of the large-scale structures was the most in the 5 kHz-excited case. The excited jet didn't only take effects on the jet shear layer, but also influenced the boundary layer. Copyright © 2009 by the American Institute of Aeronautics and Astronautics, Inc.
