Transfer Of Ultrasonic Energy

Ultrasound enhanced vacuum drying of honey was carried out at ultrasonic energy density levels of 0 04 08 12 16 Wg respectively and the drying kinetics model was established.

Transfer of ultrasonic energy. In most common UT applications very short ultrasonic pulse-waves with center frequencies ranging from 01-15 MHz and occasionally up to 50 MHz are transmitted into materials to detect internal flaws or to characterize materials.
