an acoustic coupler that facilitates acoustically coupling an acoustic device (such as an ultrasound imaging transducer or an ultrasound therapy transducer) to a physical mass, where the...

plots will help us to characterize the acoustic coupling at the corona-neutral gas surface, and, specifically, to identify the parameter dependence of the time constant of relaxation at the interface.

2021年3月3日 · An acoustic coupler connects a modem to a telephone line to transmit data from one computer to another. The acoustic coupler that Van Geen developed used an ordinary handset placed in a cradle containing a speaker and a microphone.

2017年10月20日 · Based on the experimental results, the fluid equations of the particles in the air were introduced to study the interactions among the electrons, ions, and neutral molecules in the discharge, and a numerical model for the amplitude of …

2016年7月22日 · The operation of a unipolar pulse-periodic corona discharge is considered. A new method is proposed for analyzing its properties by considering the structure of discharge-emitted sound.

2018年9月22日 · In this study, acoustic wave and pulse corona discharge coupling field were used as a pretreatment to force fine particles to agglomerate into larger particles, resulting in significantly more efficient fine particle removal.

2021年4月1日 · Herein, we propose a novel method that uses manganese oxides (MnO x) for the induced adsorption of Hg 0 to coagulate the sorbent and fine particles, assisted by bipolar corona discharge. The results showed that Hg 0 removal efficiencies increased from 10.2% to 32.2% with sorbent injection when the corona discharge was +21 kV and −24 kV ...

2021年4月1日 · A novel device in the coupling system of corona discharge and embedded turbulence was put forward and studied. Effects of polarity and strength of electric field on the particle agglomeration were investigated.

2017年5月1日 · A novel pretreatment process using the coupling effect of pulsed corona discharge and acoustic waves enhanced by spray droplets for fine particle agglomeration and capture was investigated in this study.
