Full textThe interfaces between a conductor and an insulator are generally assumed to be perfect, meaning that the Debye length in the insulator is considered to be much larger than its thickness. However, this work shows that this is not the case and that interface states generate a contact potential that can significantly alter the behavior of the interface when the material is subjected to a strong electric field. Indeed, the interface dipole responsible for the interface voltage modifies the curvature of the energy bands and thus either promotes or hinders charge injection or extraction. A series of experiments was conducted using the pressure wave method, implemented with a high-power acoustic generator on various polyethylene samples, with different electrodes and under various experimental conditions. The interface dipoles observed through measurement do indeed influence charge injection when the material is under high voltage. It is noteworthy that aluminum has a greater influence, particularly when used with silicone oil. When the insulator does not have electrodes, it is preferable to directly couple it with a carbon-filled polymer and silicone oil rather than deposit electrodes on it under vacuum. The interface dipole observed is indeed closer to that seen with carbon-filled polymer electrodes hot-bonded to the material. Upon applying voltage, charges initially penetrate the sample due to the interface dipole. The migration of these charges then leads to secondary injections caused by a field effect. Fluorinating the surface of the samples did not significantly improve the situation and thus does not act as a shield against charges, but rather as a barrier to the diffusion of impurities

Full textIn a two-dimensional open system, when the acoustic wave spreads in the tube with the presence of an obstacle, there will be the amplification of sound pressure around the obstacle. Trapped mode exists surrounding the obstacle below and above the cut-off frequency, and they bring considerable damage to the system in the form of such as noise, stability and security issues. In the previous research, they mainly concentrated on the solving of Helmholtz equation, which means that the variation of non-potential flow was not taken into consideration. The objective of this paper is to numerically compute the trapped mode with the presence of non-potential flow. Firstly, the theoretical framework of this thesis is stated. The mixed Galbrun equation, as well as boundary conditions and the associated energy properties, is represented. And then the perfectly matched layer associated with Galbrun equation is introduced. Secondly, for the analysis of trapped mode, there are already a lot of literature on numerical and physical aspects, but they have studied the trapped mode all associated with Helmholtz equation, which is primarily suitable for the case of without flow or uniform mean flow. Hence, a numerical calculation model involved with Galbrun equationwith the uniform mean flow is proposed and the obtained results are compared with those given in references. Finally, in order to consider the effects of non-potential flow. A coupling method of sound field and flow field associated with Galbrun equation is developed, and the trapped mode is captured through scanning the frequency. At the same time, the effects of various parameters of obstacles on the trapped mode are also studied

Full textA new prediction method for acoustics is proposed for the mid and high frequency range: the intensity potential approach (IPA) is based on the local power balance. The use of a finite element model respects the geometry with accuracy. A thermal conductivity analogy permits the use of existing solvers, with graphical pre-processing and post-processing tools. The use of the intensity potential avoids the "Fourier's Law" assumption relating energy and intensity, for which no evidence has been found yet in the general case. The irrotationnal intensity is computed, giving local information on acoustic energy paths, during the conception stage of industrial products. Free field pressure computation is also provided. The intensity potential approach has been validated on the full-scale mock-up of the engine compartment of a truck, by comparison with measured transfer functions and with a boundary element model. The source power in its environment is measured
