Abstract

The present work focuses on the intrinsic properties of an axisymmetric separating/reattaching flow. A numerical simulation of a compressible flow over a cylinder extended by another cylinder of smaller diameter is performed at a Reynolds number based on the diameter of the larger cylinder of 1.2 × 106. Statistical and fluctuating properties are compared with the available experimental data and those of two additional configurations. First the plane counterpart of the axisymmetric case allows us to assess the influence of three-dimensionality. Then a double backward facing step designed from the half upper part of the plane case permits us to survey the flow interactions. Finally a linear stability analysis is coupled with two-point correlations unveiling the importance of the highest coherent modes in the flow behaviour.
