Jet noise from instability mode interactions
A nonlinear interaction model is used to study sources of sound in jets. The model uses quadratic interactions of instability modes, which are obtained by solving the linear parabolized stability equations. Source terms involving nonlinear interactions are evaluated and a linear wave equation is solved with direct injection of the source terms. Thus the complete method solves only linear partia...
متن کاملShear Mode Piezoelectric Thin Film Resonators
1.1 Shear mode bulk acoustic wave devices and sensors Acoustic microsensor technique, well known as QCM (Quartz crystal microbalance) or TSM (Thickness shear mode) sensor, is an effective method to detect small mass loading on the sensor surface. This sensor can be operated even in liquid by using shear mode resonance. Therefore, shear mode piezoelectric film resonators are attractive for liqui...
متن کاملThe shear mode of multilayer graphene.
The quest for materials capable of realizing the next generation of electronic and photonic devices continues to fuel research on the electronic, optical and vibrational properties of graphene. Few-layer graphene (FLG) flakes with less than ten layers each show a distinctive band structure. Thus, there is an increasing interest in the physics and applications of FLGs. Raman spectroscopy is one ...

متن کاملComparison of Active Constrained Layer Damping by Using Extension and Shear Mode Piezoceramic Actuators
We analyze, numerically by the finite element method, three-dimensional electromechanical deformations of a thick laminated plate with layers made of aluminum, a viscoelastic material and a piezoceramic (PZT). Two arrangements of layers are considered. In one case a central PZT layer is surrounded on both sides by viscoelastic layers and aluminum layers are on the outside surfaces. The PZT is p...
