The ultrasonic data at each of the extruder functional zones are presented. The ultrasonic results have been used to evaluate an opical RTD measurement method by using an optical sensor side by side with one ultrasonic probe at the mixing zone of the extruder. The comparison of the ultrasonic ...
aUltrasonic is the name given to the study and application of ultrasound, which is sound of a pitch too high to be detected by the human ear, i.e. of frequencies greater than about 18 kHz [10]. 超音波的是名字被给超声波的研究和应用,是人的耳朵太高将查出的沥青的声音,即。 频率大于大约...
What is the Ultrasonic Sound? As already mentioned, sound can be beyond and below the human audible range. So, any sound that is higher than this range is called the ultrasonic sound. The application of ultrasonic sound is not just numerous, it is also highly beneficial. Students are require...
Ultrasonic cleaners transform low-frequency AC into high-frequency sound waves via the piezoelectric transducer, which is attached either to the bottom of the processing vessel or submerged into the cleaning liquid. The transducer produces high-intensity waves into the solution, creating compression, ...
Sounds in the sonic, infrasonic, and ultrasonic ranges are potentially useful for controlling fish behavior. However, most experiments testing the usefulness of such sounds have given ambiguous results except when ultrasound has been used to control some clupeid species. Very little is known about ...
SummaryThe possibility of developing an objective method of measuring the crispness of biscuits using the ultrasonic pulse echo technique was investigated. An encouraging relationship between the crispness (from sensory measurement) and the velocity of longitudinal sound was found. A similar, but less ...
Ultrasonic cell crushing is to convert electrical energy into sound energy through the transducer, and this energy becomes dense small bubbles through the liquid medium. These small bubbles quickly burst, producing energy like small bombs, so as to play the role of breaking cells and other substanc...
time is associated with the propagation distance and the speed of sound ， ultrasonic attenuation ， and the spectrum changes is closely related with the composition of the coupling agent and the size of the particles contained within. Therefore ， a wide range of applications in the ultrasonic ...

The velocity of sound and the density have values that are sufficiently different for liquid as compared to solid phases of metals and alloys to permit the use of pulse‐echo ultrasonic techniques to locate the solid/liquid interface during solidification and melting. Experimental results are ...
