Texte intégralIn this PhD work, sensitivity studies are carried out for turbulent shear flows using direct noise computations and the complex differentiation method.First, the complex differentiation method is applied to two-dimensional mixing layers to investigate its capacity to highlight the effects of a parameter on the aerodynamic noise.For that, direct numerical simulations of mixing layers are performed using this method for different Mach numbers, Reynolds numbers and mesh spacings.In each case, the derivatives of the noise levels with respect to one of the three parameters are obtained using the complex differentiation method.The results are in good agreement with others from the literature and parametric studies.They indicate that the complex differentiation method can be used to describe the effects of physical parameters and of the grid resolution on the sound produced by a high-speed flow.Secondly, the complex differentiation method is applied to the study of the receptivity mechanism occurring when an acoustic wave reflects at the nozzle lip of a jet.For this purpose, using the results of a simulation of a jet impinging on a plate, an imaginary amplitude acoustic pulse is introduced at a given time in the near-nozzle region outside the jet.The sensitivity of the near-nozzle mixing layers to an acoustic disturbance is then determined using the complex differentiation method.This sensitivity is used to highlight the excitation of an instability wave by the acoustic disturbance.Finally, the influence of nozzle-exit conditions (velocity profile and turbulence level) on the tonal noise components generated by subsonic impinging jets is investigated.For that, jets with different nozzle-exit velocity profiles, several boundary-layer excitation levels, at Mach numbers of 0.6 or 0.9, impinging on a plate located at 6 or 8 nozzle radii from the nozzle, are simulated.The results show that the nozzle-exit conditions significantly affect the amplitude of the tonal noise components and that impinging jets at Mach numbers below 0.65, which are generally non-resonant, can be resonant for specific nozzle-exit conditions.The effects of the nozzle-exit conditions are found to result from changes in the development of the jet mixing layers, which lead to differences in the amplification properties of the Kelvin-Helmholtz instability waves between the nozzle and the plate, and in the energy contained in the coherent structures of the jets near the impingement region
