Keywords: axisymmetric lobed mixer, confined flow, fuel/air mixing

The confined flow-field of an axisymmetric lobed mixer was studied. Both numerical and experimental results indicate that the streamwise vortices start to breakdown at three wavelengths downstream of the mixer, which is much shorter than that of planar lobed mixers subject to parallel freestreams.
