Vibration analysis of small-scale piezoelectric plates in contact with fluid

In this article, according to the application of vibration analysis of small-scale piezoelectric plates in the design and development of modern electromechanical systems, for the first time, the vibrations of a small-scale piezoelectric plate in contact with a moving viscous fluid have been modeled. In order to consider the effects of small scales on the vibration behavior of the system, the theories of non-local elasticity and surface energy have been used simultaneously. The interaction between the fluid and the small-scale piezoelectric plate has been modeled using the Navier-Stokes equations. the effect of fluid parameters and plate geometry as well as applied voltage on the natural frequencies of small-scale piezoelectric plate was studied. The results presented in this research for the design of smart devices. Also, it is very useful to predict the voltage required for the vibration of fluid-coupled piezoelectric plates for the desired frequency of the designer.
