چکیده
The article presents the results of development works and research on atomization process carried out using two prototype high-power ultrasonic systems. Ultrasonic systems have been designed to develop a new metal powder production process; these materials are increasingly used in modern manufacturing processes such as additive technologies or spraying surfacing processes. preliminary studies presented were conducted for water assess effectiveness both verify theoretical structural assumptions. In atomization, wave causes phenomenon cavitation, which leads overcoming surface tension forces liquid its disintegration into fine droplets. important parameters that affect properties produced droplets include, among others, frequency sonotrode vibrations amplitude working plate. As part research, paper selecting geometry different values transducer’s natural frequencies (20 kHz 70 kHz). design process, finite element method was perform harmonic analysis assumptions presented. modeled then waveguides verified experimentally by measuring deflection distribution plate high-precision laser displacement sensor. Then, work ultimately resulted conducting tests water. obtained aerosols mechanism their formation studied high-speed camera. Finally, Matlab R2020a software image scripts, it possible analyze droplet size generated It observed 50% range 35–55 μm 20 system, while system 10–25 μm, is very satisfying terms atomization.

This paper examines two mixed-signal hardware circuits dedicated to transient power system emulation. They both use a flexible, modular and very high-speed emulation approach based on a field programmable power network system (FPPNS). This promising approach is dedicated to emulate multiple nodes power system dynamics. The speed limit of such approach overcomes the numerical simulators because ...
متن کاملUltrasonic atomization of tissue and its role in tissue fractionation by high intensity focused ultrasound.
Atomization and fountain formation is a well-known phenomenon that occurs when a focused ultrasound wave in liquid encounters an air interface. High intensity focused ultrasound (HIFU) has been shown to fractionate a tissue into submicron-sized fragments in a process termed boiling histotripsy, wherein the focused ultrasound wave superheats the tissue at the focus, producing a millimetre-sized ...
متن کاملUltrasonic atomization of liquids in drop-chain acoustic fountains.
When focused ultrasound waves of moderate intensity in liquid encounter an air interface, a chain of drops emerges from the liquid surface to form what is known as a drop-chain fountain. Atomization, or the emission of micro-droplets, occurs when the acoustic intensity exceeds a liquid-dependent threshold. While the cavitation-wave hypothesis, which states that atomization arises from a combina...
