Use of modern simulation for industrial applications of high power ultrasonics

摘要

The numerical simulation of high power ultrasonic devices is a highly challenging task, since a multi-field problem based on nonlinear partial differential equations has to be solved. We will concentrate on the numerical simulation of piezoelectric and electromagnetic pulsed acoustic power sources as well as on a piezoelectric driven cw-source. Our calculation scheme is based on the Finite Element Method. It is capable to handle both the transducer and acoustic nonlinearities. Practical applications will demonstrate the applicability of our simulation scheme.
