Full textDuring open jet wind tunnel measurements, the acoustic waves emitted by a device or an acoustic source located inside the flow propagate inside the turbulent shear layer that develops at the periphery of the jet before being received by microphones located outside the flow. The acoustic wave interacts with the turbulent velocity field leading to a change of directivity, a phase and amplitude modulation as well as a spectral re-distribution of the acoustic energy over a band of frequencies. This phenomenon is known as acoustic scattering. This work has consisted in the study of the scattering of an acoustic wave by a turbulent shear layer using large-eddy simulation. The first step of the study has consisted in the large-eddy simulation of a turbulent shear layer in its self-similar state. In a second second step, the direct computation of the interaction between the acoustic wave and the turbulent flow has been performed in order to study the characteristics of the resulting scattered pressure field. It has been shown that the numerical simulation is able to accurately predict the frequencies on which the main part of the scattered energy is redistributed, as well as the shape of the scattered pressure spectrum. Finally, the turbulent velocity field which is correlated with the envelope of the scattered pressure field is reconstructed using the linear stochastic estimation method. This method has enabled the visualization of the large turbulent structures that mainly take part in the acoustic scattering mechanism

Full textThe aim of this study is to understand the dynamics of a complex flow: a mixing layer - wake interaction. This flow, 3D and inhomogeneous in all three directions, is first analyzed with hot wire and wall pressure measurements. From those data, the Reynolds number, the aspect ratio and the shear parameter influence have been analyzed on the Strouhal number, the base pressure coefficient and the vortex-formation length. In particular, analyses show that, above the impact area of the mixing layer (the low velocity side), the spectral analysis systematically shows at least two cells of different frequency. The main organization is then analyzed by means of PIV (Particle Image Velocimetry) and of POD (Proper Orthogonal Decomposition). First POD modes, which are representative of the energetically dominant coherent structures, clearly show the presence of oblique structures on each side of the mixing layer impact area. In the high velocity zone, where flow is three-dimensional, the higher POD modes show linkages of structures, longitudinal structures and dislocation of structures, close to those found at the time of the wake three-dimensionalisation (both by their intrinsic nature or by perturbations along the span of the cylinder). In addition, a LODS (Low Order Dynamical System) is constructed using a Galerkin projection in the plane behind the cylinder axis. The analysis reveals the existence of a low beating frequency of an injecting flow on the high velocity side. Lastly, low Reynolds number simulated data comfort experimental results on the characteristic behaviour for this flow configuration
