Measurement of the 3D turbulent flow field of an annular jet and Proper Orthogonal Decomposition analysis.
Abstract : The annular jet is an example of complex shear flow situations. Two axisymmetric shear layers, originating at the jet exit, one at the nozzle lip and the other at the centre body, eventually meet downstream or interact with each other. The main aim of this study is to observe and analyze the 3D turbulent flow field on an annular jet with a great diameter ratio (r= 0.91). Measurements are conducted with a Reynolds number ReDo=107800. This work will permit us essentially to have a better knowledge of annular jets which present the effect of asymmetries in the experimental jet exit velocities and to meet manufacturers' needs.
