An efficient approximation for the vibro-acoustic response of a turbulent boundary layer excited panel

A modal analysis is then performed using the linearized boundary conditions which can also be used to compute the suitable blowing pressure and the suitable pipe length to obtain

The goal of this experiment is to characterize the broadband airfoil noise in static (fixed angle of attack) and dynamic (oscil- lating airfoil) configurations.. The experiments

Les besoins grandissants pour le développement de nouvelles technologies compactes, performantes et moins couteuse sont des défis à relever pour les systèmes de

Indeed, if the acoustic approximation of elastic P-waves is natural for homogeneous isotropic me- dia, it is not the case anymore for anisotropic media nor for heterogeneous media

The direct approach uses several cleaning methods applied to the measured wall pressure fluctuation, and the indirect approach is based on the identification of the pressure

Influence of the transverse isotropic model for the GRP layer: Radial stress at the receiving point for normal and oblique (45 ◦ ) incident plane wave. Differences are observed on

LMS Pre-acoustics software was used to mesh the engine (811 elements) and the engine mesh was distributed into six groups (engine faces) in order to simulate
