- Abstract
Ultrasounds are oscillations in the field of 18 KHz....100 KHz, which has proven its applicability through many applications starting from the industrial field (ultrasonic defectoscopy, ultrasonic cleaning, etc.) pass through the field of consumer goods (ultrasonic motors, systems operating cameras, high‐precision microscopes, etc.) and reach the medical field such as ultrasound investigations, extremely used today. One of the less known and very new applications at present, but which is trying to make a very important contribution in the field of ecotechnology is the filtration of air by ultrasonic cavitation. In order to achieve air filtration using the phenomenon of ultrasonic cavitation, the ultrasonic system consisting mainly of the ultrasonic transducer must be optimally attached to the lower part of the tank where the air filtration process takes place. In this sense, by modeling and simulation by the finite element method, the thickness of the adhesive layer is determined so that the phenomenon of ultrasonic cavitation to occur efficiently and for a long operating time. Considering the phenomenon of ultrasonic cavitation, the presented research proposes a new method of industrial air filtration in which impurities and inhomogeneities of impure air are germs for the formation of cavitation bubbles so that this phenomenon will lead to their elimination resulting in a higher quality filtered air. The phenomenon of ultrasonic cavitation occurs due to a system of piezoceramic transducers mounted on the bottom of tank. One of the very important problems during the experiments is the fixation of the piezoceramic transducer system on the bottom surface of the tank. This is done with the help of a silicone adhesive that must allow an optimal transfer of the ultrasonic oscillations from the ultrasonic transducer. Thus, determining the thickness of the silicone adhesive layer becomes very important and this is done by performing a modal analysis using the finite element method.
