| dc.description.abstract | 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. | en_US |
