This work is concerned with systems possessing cyclic symmetries. In particular, we concentrate on the case in which the medium possesses infinite order cyclic symmetry, while the constitutive relations have cyclic symmetry of a lower order. We investigate the interactions between modes ... Mehr lesen
Due to the increasing demand for hydrogen gas sensors for applications such as automation, transportation, or environmental monitoring, the need for sensitive and reliable sensors with a short response time is increasing. This paper presents an empirical model that studies the ... Mehr lesen
Achieving passive device working over two GHz bands for next generation mobile phone has been strongly desired. This paper investigated the spurious mode suppression for the BAW resonator. The border-frame technique which has been proposed in many literatures is examined here ... Mehr lesen
Turbomachines blades are forced by a load resulting from the interaction with the fluid. The consequent vibrations, and the associated fatigue phenomena, can give catastrophic failures and the reduction of the blades life. It could be increased if damping system are used. The ... Mehr lesen
This work focuses on the application of multiphysics finite element simulations in the manufacturing and application of high power ultrasonic machines. Industries providing big power ultrasonic solutions as in cleaning, welding, sonochemistry and cutting fields, already apply the finite ... Mehr lesen
This work describes the design methodology and development of piezoelectric transducers for applications in fluids with COMSOL_Multiphysics. In these linear models for the acoustic-structure interaction approximate numerical solutions have been obtained. In order to perform the ... Mehr lesen
Microgrippers are typical MEMS devices used to pick, hold and transport micro-objects. Microgrippers are widely used in the field of micro-assembly, micro-surgery and manipulation of micro-particles. Thermal microgrippers are widely used for large displacement, high accuracy and ... Mehr lesen
This paper discusses the simulation studies on a vibration based energy harvesting system to convert the undesirable mechanical vibration to useful green power. The design consists of a resonating proof mass and a spring system enclosed in housing and fixed on the source of vibration. A ... Mehr lesen
In this paper some discrete parts of a valveless piezoelectric micropump for drug delivery system is designed and simulated. The core components of the micropump are actuator unit that converts the reciprocating movement of a diaphragm actuated by a piezoelectric actuator into a pumping ... Mehr lesen
Cantilever beam-type transducers have been in great demand and explored widely in the recent years, typically in thin film form because of their sensor and actuator applications. The piezoelectric cantilever is the most preferred structure employed in technological applications. ... Mehr lesen
