Gas Turbine and Plasma Dynamics Laboratory TJ778.M41 G24 no.143 Turbulence Mixing September 1978 Originally presented as the author's thesis, Sc. D. in the M.I.T. Dept. of Aeronautics and Astronautics, 1979 Includes bibliographical references (leaf 49) The effect of swirl on the mixing of two gas streams of the same density in coaxial annular geometry has been examined. The flow is studied via a fluorescent tracer, 2-3 biacetyl. Through direct excitation, collisional excitation, and collisional de-excitation of the tracer, the turbulent transport, molecularly mixed and unmixed regions in the flow are visualized. A three dimensional structure flattened in the azimuthal direction is observed. It is suggested that this structure is the result of the growth of the unstable azimuthal modes as limited by a turbulent eddy viscosity.
