The results show that with the increase of ultrasonic power in the range of 60 140 W, the mechanical effect and the acoustic streaming effect of ultrasonic increase the area of molten pool and the width of cladding layer.
We suggest three methods to analyze the acoustic streaming on our ultrasonic air pump and compared these calculated and experimental results in the sound pressure distribution and the flow velocity distribution in the air gap.
This study examines the qualitative and quantitative properties of water-based suspensions and the effect on the occurrence and threshold levels of ultrasonic phenomena, standing wave, acoustic streaming and especially cavitation.
More studies will be needed to investigate the efficacy of the aid of different irrigation systems (such as ultrasonic irrigation, photon-induced photoacoustic streaming, and multisonic ultracleaning system) and the combined use of NaOCl and EDTA with water in between to keep DT open during CSP.
Streaming detection is an ultrasonic technique that can be used to distinguish fluid-filled lesions, or cysts, from solid lesions.
Streaming Detection is a new ultrasonic technique proposed to distinguish fluid-filled lesions, or cysts, from solid lesions in the breast.
Ultrasonic and elasticity imaging, specifically nonlinear propagation, acoustic streaming and radiation force; the intentional generation of these phenomena for the purpose of tissue characterization; finite element modeling of normal and diseased tissue when exposed to ultrasound, and performing both phantom and clinical experiments investigating these phenomena.
Therefore, the rational design of scaled-up ultrasonic reactors requires the quantitative prediction of acoustic streaming, power dissipation, mass transfer and cavitational activity in the reactor by theoretical simulations [ 19].
The mechanisms for these ultrasonic applications can be illustrated by a series of ultrasonically induced effects such as acoustic cavitation, streaming and vibration.
The application of ultrasonic energy at high power to a liquid produces acoustic streaming and shear forces by cavitations in a liquid, which leads to reduced membrane fouling and increased permeate flux [ 121].
OBJECTIVE: Streaming detection is a novel sonography technique that uses ultrasonic energy to induce movement in cyst fluid that is detected on Doppler sonography.
