The interaction of axisymmetric and streamwise vortices in the axisymmetric mixing layer developing along the jet boundary was investigated by a flow visualization technique. The jet was excited by axial and azimuthal perturbations to stabilize and enhance axisymmetric and streamwise vortices. A laser fluorescent dye and a laser light sheet were used to visualize the mixing layer. The three-dimensional views of the boundary surface of mixing layer were constructed by applying the Taylor hypothesis to the cross-sectional images. By the three-dimensional views, the interaction of axisymmetric and streamwise vortices was revealed, and the entrainment rate of the jet was also discussed in relation to the vortical structure.
