The driving force behind the improvement of drying technologies is the need to both produce
better quality products (Chou and Chua 2001) and save energy. Despite the fact that …

A new type of high power composite ultrasonic transducer was proposed and studied. The
composite transducer consists of a sandwich longitudinal piezoelectric transducer, an …

This paper aims to provide an alternative method to determine the characteristics of a
piezoelectric transducer from measurement. A block diagram approach is proposed to …

The design and simulation of power transducers are difficult since piezoelectric, dielectric
and elastic properties of ferroelectric materials differ from linear behavior when driven at …

This paper presents a new high power ultrasonic (HPU) radiator, which consists of a
transducer, an ultrasonic horn, and a metal circular ring. Both the transducer and horn in …

The influence of transducer-electrode and electrode-wall gaps on the spatial distribution of
the acoustic pressure inside a sonoelectrochemical reactor has been studied by employing …

Ultrasonic welding is used across variety of industries to join together thermoplastic
materials. During ultrasonic welding, high frequency mechanical vibrations and compressive …

In this paper, a new type of high power ultrasonic radiator used in liquid is studied. The
proposed ultrasonic radiator is a metal cylinder with comparative radial and longitudinal …

Design for reliability (DfR) of ultrasonic bone knife starts at the early design phase and can
greatly improve the safety of surgery which is especially crucial for patient's life. By failure …

No ultrassom diagnóstico faz-se uso de ondas acústicas de baixa intensidade para
investigar os tecidos biológicos, sendo uma técnica não invasiva. Ondas ultrassônicas de …
